Tantilla Onomastic: Annotated Etymology and Taxonomy of the Genus Tantilla

Onomastic of Tantilla - Page | 1 ONOMASTIC OF SNAKE SPECIES SCIENTIFIC NAMES Snake species in the genus Tantilla Masud Salimian Morgan State university Overview Tantilla is a genus of small, secretive colubrid snakes in the subfamily Colubrinae, commonly referred to as centipede snakes or black-headed snakes. Distributed from the southern United States through Central America and into much of South America, the genus includes 74 recognized species as of today and is particularly diverse in Mexico and Central America. Tantilla snakes are slender, fossorial, and nocturnal, often encountered only by careful searching in leaf litter or beneath surface debris. Despite their wide range, many species remain poorly understood due to their secretive habits and miniaturized body size. Natural History Tantilla species typically inhabit forested, semi-arid, or montane environments with loose soil, abundant leaf litter, or decomposing logs that facilitate burrowing. Most species are nocturnal and fossorial, surfacing after rains or during high humidity periods. Their diet is highly specialized, with many species preying primarily on arthropods—especially centipedes (e.g., Scolopendra spp.), spiders, beetle larvae, and occasionally soft-bodied insects. The common name "centipede snake" reflects this dietary focus. Feeding is usually done by rapid subjugation of the prey, which may involve mild venom. Despite their secretive nature, Tantilla species can sometimes be locally abundant and play important ecological roles as predators of soil-dwelling arthropods. Reproduction and Sexual Dimorphism All known Tantilla species are oviparous, laying small clutches (typically 2–5 elongate eggs) in moist, hidden locations such as under logs or within burrows. In some regions, reproduction is seasonal, with egg-laying often timed to coincide with the onset of the rainy season to ensure hatchling emergence when prey is most abundant. Sexual dimorphism is usually subtle. Males tend to have relatively longer tails and slightly narrower heads, while females may be slightly larger in body girth. In field settings, sex determination often requires probing or inspection of the tail base and cloacal region. Dentition and Hemipenial Morphology Tantilla snakes are opisthoglyphous (rear-fanged), with a pair of enlarged posterior maxillary teeth connected to Duvernoy’s glands. These fangs are not grooved deeply, and the secretions are likely only mildly toxic to humans but possibly effective at immobilizing invertebrate prey such as centipedes. The hemipenes of Tantilla are generally unilobed or weakly bilobed and often ornamented with small spines or papillae. Hemipenial morphology varies among species and provides useful taxonomic characters, particularly where scalation and coloration are insufficient for reliable identification. Scalation Onomastic of Tantilla - Page | 2 Scalation across Tantilla species is generally conservative but diagnostically useful. Dorsal scales are smooth and usually arranged in 13–15 rows at midbody. Ventrals number from ~100 to 180, depending on the species, and subcaudals are usually paired. Head scalation includes a divided anal plate and smooth, often glossy head shields. The rostrum is small and blunt, suited to burrowing, and many species have a distinctive dark or black cap or head marking, often sharply contrasted with the lighter body. Coloration is typically earthy—shades of tan, reddishbrown, or gray—sometimes with faint striping or banding. Venters are usually pale, occasionally with dark margins. The characteristic black or dark brown head cap is a diagnostic trait in many species, although it varies in extent and intensity. Venom Tantilla species possess Duvernoy’s glands associated with rear fangs, and their secretions are considered mildly venomous—harmless to humans but potentially useful in subduing invertebrate prey, especially centipedes. These secretions likely aid in breaking down tough exoskeletons or immobilizing fast-moving arthropods. There are no confirmed cases of significant envenomation in humans by Tantilla, and their small size and reluctance to bite further reduce any risk. Historical Notes The genus Tantilla was established by Baird and Girard in 1853, with Tantilla coronata as one of the earliest described species. Over time, species have been described across a wide geographic range, with Mexico and Central America emerging as hotspots of Tantilla diversity and endemism. Taxonomic challenges have long plagued the genus due to the subtle external differences among species, intraspecific variation, and under-sampling of many populations. Molecular phylogenetics, combined with hemipenial and osteological studies, have improved the resolution of species boundaries and clarified relationships with closely related dipsadine and colubrine taxa. In recent decades, several cryptic or new Tantilla species have been described, and many more may await discovery in understudied regions of Mesoamerica and the Andes. As small, fossorial predators of ecological importance, Tantilla continues to be a relevant genus for studies on diet specialization, fossorial adaptation, and snake microendemism. Genus Tantilla Baird & Girard, 1853 The genus name Tantilla is a Latin diminutive noun, feminine, first declension. It derives from tantillus, itself the diminutive of tantulus ("so little," "so small.") In turn, tantulus is the diminutive of tantus ("of such size," or "so great,") formed from the adverb tam ("so,") and the adjectival ending -tus. Thus, Tantilla literally means "very small one," or "a very small thing," a direct reference to the small body size typical of species assigned to this genus. Remarks: Although earlier interpretations sometimes treated Tantilla as an adjectival formation, its morphology places it squarely among the Latin diminutive nouns in -illa, a productive class that includes patella, lamella, fontanella, scutella, etc. Tantilla behaves grammatically as a feminine noun, not as an adjective. Under the ICZN Code (Art. 22.1), any genus-group name, whether originally a noun or not, "must be treated as a noun in the nominative singular case." Tantilla, already a fully formed Latin noun, conforms naturally to this requirement. [Edited incorporating comments by Dr. Petr Necas]. Onomastic of Tantilla - Page | 3 Species Tantilla albiceps BARBOUR, 1925 The species epithet albiceps is color-based morphology descriptor of body parts. It is a Latin adjective formed from albi- (from albus, meaning "white") and -ceps (from caput, meaning "head"), literally translating to "white-headed." It refers to the almost completely white coloration of the head and nape in this species. Grammatically, it is a nominative feminine singular adjective of the third declension, one-termination adjective agreeing with the genus name Tantilla (treated as feminine noun.) Publication Quote: "A small very slender Tantilla with head and nape almost wholly white." Tantilla alticola (BOULENGER, 1903) The species name alticola is a habitat-based toponymic descriptor. It is a compound Latin adjective derived from participle altī which is the inflection of altus ("high," or "tall,") and compound word element -cola, from the verb colere ("to inhabit," "dwell," or "cultivate") and is used to create a compound noun with the meaning "one who inhabits". When -cola is attached to a preceding noun (or noun stem) it indicates the type of place which is inhabited ("one who inhabits the high [altitude]," or "high [altitude]-dweller,") It has semantic similarity to moticola ("mountain-dweller.") though alticola alludes to higher altitudes. It is a reference to the habitat of the species as the type locality is from Santa Rita, north of Medellin, Colombia, [elevation] 9000 feet = 2743 m. Grammatically, it functions as a noun in apposition. Publication Quote: "Three specimens (males and young) from Santa Rita, north of Medellin, Colombia, altitude 9000 feet." Tantilla andinista WILSON & MENA, 1980 The species name andinista is a habitat-based toponymic descriptor. It not a Latin but a Spanish word meaning "wanderer among the Andes." It is a reference to the habitat of the species in Andes mountains. The specific type locality is "5 km E Alausi, Prov. Chimborazo, Ecuador, elevation 2600-2750 m." As a non-Latin noun (or a noun-like word derived from a modern language), it functions as a noun in apposition. Publication Quote: "The name andinista is from the Spanish, meaning "wanderer among the Andes" in allusion to the montane distribution of this species." Remarks: The species name andinista—referring to the Andes Mountains—highlights its distribution within one of the world's most significant centers of species richness. Within the Andean system, the contrast between slopes is often critical for habitat partitioning. Generally, the Pacific slopes of the Andes are characterized by high humidity and dense cloud forests, which often harbor distinct reptile communities due to heavy rainfall and coastal influence. Conversely, the eastern slopes, which descend into the Amazon basin, experience different temperature and moisture regimes, often supporting species adapted to high-elevation humid montane forests or páramo ecosystems. For a genus like Tantilla, understanding which side of the mountain ridge a species is found is crucial, as it often dictates specific microhabitat requirements and limits gene flow between populations.

It is a Latin adjective in feminine form of armillātus ("ornamented with a bracelet,") which is formed from armilla ("bracelet") and adjectival suffix -ātus for "provided with" or "having the nature of," literally translating to "having a bracelet." Grammatically, it is a first/second-declension, three-termination, nominative singular adjective, agreeing in gender and case with the genus name Tantilla (treated as feminine noun.) Publication Quote: "... head and nape for five scales, black, with a yellow spot... The black is bordered behind by a yellow collar of two scales width, which is also bordered by black behind except where it sends off on the third and fourth rows of scales." Tantilla atriceps (GÜNTHER, 1895) The species epithet atriceps is color-based morphology descriptor of body parts. It is a Latin compound adjective formed from atri- (from ater, meaning "black") and -ceps (from caput, meaning "head"), literally "black-headed." It refers to the black coloration of the head in this species. Grammatically, it is a nominative feminine singular adjective of the third declension, one-termination adjective agreeing with the genus name Tantilla (treated as feminine noun.) Onomastic of Tantilla - Page | 5 Publication Quote: "... upper part of the head blackish, bordered behind by a narrow, straight, white, transverse collar, crossing the neck behind the occipitals. No white spots on the head." Tantilla atriceps, Mexican Black-headed Snake - Villaldama, Nuevo Leon, Mexico - Michael Price https://www.inaturalist.org/people/wild-about-texas Creative Commons License Tantilla bairdi STUART, 1941 The specific epithet bairdi is an eponymous descriptor. It is a patronymic epithet, a proper name Latinized and put into the genitive case. The ending -i indicates that it honors a male individual. It honors Spencer Fullerton Baird who also described the genus. Remarks: Spencer Fullerton Baird (February 1823 – August 1887) was a prominent American naturalist, ornithologist, and zoologist who held significant roles in several major scientific institutions, most notably serving as the Secretary of the Smithsonian Institution from 1878 until his death. He was instrumental in developing the United States National Museum's collections and was a driving force behind systematic biological surveys in the United States. Baird's broad expertise and influence on 19th-century American natural history, including herpetology, make his commemoration in the Tantilla onomastics a nod to his foundational role in the field. Tantilla berguidoi BATISTA, MEBERT, LOTZKAT & WILSON, 2016 The specific epithet berguidoi is an eponymous descriptor. It is a patronymic epithet, a proper name Latinized and put into the genitive case. The ending -i indicates that it honors a male individual. It honors Guido Berguido, founder of the Adopt Panama Rainforest Association. Onomastic of Tantilla - Page | 6 Remarks: Guido Berguido is noted as the founder of the Adopt Panama Rainforest Association (APRA), an organization dedicated to the conservation of Panama's rainforest ecosystems. His efforts through APRA focus on land preservation and ecological stewardship, which directly supports the habitats of many Neotropical species, including those in the snake genus Tantilla. His work is recognized in the onomastics for his strong commitment to protecting the biodiversity of Panama. Tantilla bocourti (GÜNTHER, 1895) The specific epithet bocourti is an eponymous descriptor. It is a patronymic epithet, a proper name Latinized and put into the genitive case. The ending -i indicates that it honors a male individual. It honors French naturalist Marie Firmin Bocourt. Remarks: Marie Firmin Bocourt (1819–1904) was a distinguished French zoologist and paleontologist, though he is perhaps best remembered for his significant contributions to herpetology through his extensive involvement with the monumental work Reptiles, Poissons, Insectes in the section of the series dedicated to reptiles. His detailed descriptions and illustrations, often produced as part of the Mission scientifique au Mexique et dans l'Amérique Centrale, provided essential foundational knowledge on Mexican and Central American reptiles, including the snakes that would later be classified within the Tantilla genus. Tantilla bocourti, Bocourt's Black-headed Snake - Presa Los Alamitos, El Garruño, Aguascalientes, Mexico - Bruno Valente https://www.inaturalist.org/people/bruno_valente Creative Commons License Onomastic of Tantilla - Page | 7 Tantilla boipiranga SAWAYA & SAZIMA, 2003 The species name boipiranga is a color-based toponymic descriptor. It not a Latin but a Tupi (native Brazilian language) word. It is composed of mboi or boi ("snake,") and piranga ("red,") literally meaning "red snake." It is a reference to the distinct reddish-orange color of the species, a similar pattern observed in Tantilla rubra and according to authors, "may mimic the similarly colored colubrids of the genus Phalotris." As a non-Latin noun (or a noun-like word derived from another language), it functions as a noun in apposition. Publication Quote: "A noun in apposition, from "mboi" or "boi" (snake) and "piranga" (red), meaning red snake in the Tupi native Brazilian language, used in allusion to the distinct reddish orange color of the new species." Tantilla boipiranga - Jaboticatubas, State of Minas Gerais, Brazil - Marco Aurelio de Sena https://www.inaturalist.org/people/marco_sena Creative Commons License Tantilla brevicauda MERTENS, 1952 The species epithet brevicauda is a morphology-based descriptor of body parts. It is a Latin noun formed from adjective brevis ("short,") and noun cauda ("tail,"), translating to "short tail." It is in reference to the relatively small number of subcaudals (hence, short tail), a characteristic of this species. It means that it refers specifically to a comparatively shorter tail of the species relative to Onomastic of Tantilla - Page | 8 other populations of species of Tantilla in its range. Grammatically, it is used here as a noun in apposition. Tantilla briggsi SAVITZKY & SMITH, 1971 The specific epithet briggsi is an eponymous descriptor. It is a patronymic epithet, a proper name Latinized and put into the genitive case. The ending -i indicates that it honors a male individual. It honors William E. Briggs (name was regrettably cited with an incorrect middle initial in the original publication), then Dean of the College of Arts and Sciences of the University of Colorado at Boulder. Remarks: William Egbert Briggs (1925–1999) was a distinguished Professor of Mathematics and served as the Dean of the College of Arts and Sciences at the University of Colorado from 1964 to 1980, confirming the honoree's prominent position at the university mentioned by the snake's authors. While his primary career was in academic administration, holding a leadership position at a major university, his inclusion in the onomastics of Tantilla suggests a contribution to herpetological research or collection support that was recognized by the taxonomist (likely Hobart M. Smith, given the other names). Deans or other senior academic figures are sometimes honored for institutional support, fundraising, or personal scientific contributions made earlier in their careers. Tantilla calamarina COPE, 1866 The species epithet calamarina is a morphology-based descriptor of size. It is the feminine form of the Latin adjective calamārius ("relating to a writing reed,") itself formed from calamus ("reed," or "cane,") and -ārius meaning "of," or "belonging to." Cope does not provide any indication of why the name was chosen; however, it is likely a reference to the slender habitus of this species that Cope resembled it to a writing reed. Remarks: Although there is no doubt about the Latin root of the epithet, any attempt to relate it to resemblance to species in Calamaria genus is possibly false, although grammatically feasible (calamaria, or calamari- + -inus indicating "of the nature of," or "resembling," literally translating to "Calamaria-like.") There is no evidence that Cope ever described any species in Calamaria and although as a taxonomist he must have been familiar with some species in that genus it was not his usual type of species he was dealing with. Cope's work primarily focused on New World reptiles, while the genus Calamaria (dwarf reed snakes) is entirely Asian. Attributing a name to another taxonomist's obscure genus without explicit indication is generally avoided when a clearer descriptive meaning (slenderness/reed-like) is available and fits the organism's morphology. The simplest and most direct reading that describes the snake itself is usually preferred. Tantilla capistrata COPE, 1875 The species epithet capistrata is a pattern-based morphology descriptor of a coloration. It is the feminine form of the Latin adjective capistratus which is formed from noun capistra [nominative of capistrum, formed as capi(ō) meaning "seize," and the suffix -trum (suffix forming instrument nouns from verbs.)] The second-declension noun, capistrum, means "halter," "headstall," or "harness." Grammatically, capistratus is a first/second-declension nominative singular adjective, agreeing in gender and case with the feminine genus Tantilla. It refers to the special pattern of color on the head of the species resembling a halter or headstall (the part of a bridle that fits over a horse's head.) - See the species image. Onomastic of Tantilla - Page | 9 Publication Quote: "‘A black half collar connected with the black crown by a longitudinal bar." Tantilla capistrata, Capistrata Centipede Snake - Macara, Ecuador - sanchezgc https://www.inaturalist.org/people/sanchezgc Creative Commons License Tantilla carolina PALACIOS-AGUILAR, FUCSKO, JIMÉNEZ-ARCOS, WILSON & MATASILVA, 2022 The specific epithet carolina is an eponymous descriptor. It is a patronymic epithet; a proper name used as a name in apposition. It is honoring the Hungarian Freedom Fighter Karolina Laszló, in recognition of her dedication to the maintenance of human rights for all peoples in the face of totalitarianism, beginning with the Hungarian Revolution in 1956. Grammar Notes: Although the epithet carolina is treated as a noun in apposition under ICZN rules, and therefore remains unchanged regardless of gender, it is not a classical Latin noun in apposition. In Classical Latin, a personal name used to honor an individual would normally be expressed in the genitive case, here as carolinae ("of Carolina,") indicating dedication or possession. Thus, while the ICZN accepts carolina as published, its form represents a departure from classical Latin morphology. Several other Tantilla eponyms follow similar modern, nonclassical patterns. Tantilla cascadae WILSON & MEYER, 1981 Onomastic of Tantilla - Page | 16 the feminine form of montānus ("of or pertaining to a mountain," or "of or "situated among mountain.") Together it translates to "mountain island." Grammatically, it is a first/seconddeclension three-termination nominative singular adjective, agreeing in gender and case with the feminine genus Tantilla. It is a reference to the type locality of the species as the type locality is from Rio Minas, 15.1 km W Santa Isabel, elevation ca. 1250 m elevation, Prov. Azuay, Ecuador. Remarks: The "mountain island" concept may need some clarification. The location is in the Andes Mountain Range of Ecuador, specifically within the Azuay Province. The Andes create a complex, varied topography, with steep slopes and deep valleys. In biogeography, a "sky island" or "mountain island" refers to a mountain or mountain range that is isolated from other mountains by significantly different habitats at lower elevations, such as forests or desert plains. This isolation can lead to unique evolutionary adaptations, as distinct populations of organisms are confined to the higher altitudes. The type locality is located at an elevation of about 1,250 meters. The surrounding lowlands, with different climatic conditions and vegetation, effectively isolate the mountain-dwelling species, much like a true island isolates oceanic species. The higher elevations of the Andes in this region, which can reach up to 4,500 meters, create a stark elevational gradient that contributes to this isolation. Tantilla jani (GÜNTHER, 1895) The specific epithet jani is an eponymous descriptor. It is a patronymic epithet, a proper name Latinized and put into the genitive case. The ending -i indicates that it honors a male individual. It honors Austrian-born botanist and professor in Parma and Milan, Italy, Giorgio Jan. Remarks: Giorgio Jan (1791–1866) was an influential Italian naturalist and physician who made significant contributions to the fields of zoology and botany. He is particularly recognized for his work in systematic biology, where he described and classified numerous species, including reptiles. His publications detailed extensive observations from his travels and studies, contributing substantially to the understanding of biodiversity during the 19th century. Smith (1912–2013), in his onomastic work, likely honored Jan for his foundational efforts in herpetological taxonomy, as Jan's earlier classifications laid groundwork for later scientists studying snakes like those in the genus Tantilla. Tantilla johnsoni WILSON, VAUGHN & DIXON, 1999 The specific epithet johnsoni is an eponymous descriptor. It is a patronymic epithet, a proper name Latinized and put into the genitive case. The ending -i indicates that it honors a male individual. It is honoring Dr. Jerry D. Johnson, a friend and colleague of the authors. Remarks: Jerry D. Johnson is a highly respected American herpetologist and professor emeritus from the University of Texas at El Paso (UTEP), honored with the species name Tantilla johnsoni by his colleagues for his significant contributions to the field. A Vietnam veteran, Johnson spent his career focused on the systematics, ecology, and conservation of amphibians and reptiles, particularly in Mexico, Central America, and the southwestern USA. In addition to his academic roles at UTEP, which included serving as Curator of Herpetology and Director of the Indio Mountains Research Station, he has been a prolific author and editor, sharing his expertise and shaping the careers of numerous students. Tantilla lempira WILSON & MENA, 1980 The specific epithet lempira is an eponymous descriptor. It is a patronymic epithet, a proper name used as a name in apposition. It is honoring the Indian chief Lempira who fought against Onomastic of Tantilla - Page | 17 the Spanish invasion of Honduras. Meaning "Lord of the Mountains" in the Lenca language, Lempira is also the name of one of 18 administrative departments in Honduras, and the name of official currency of the country. Historical Notes: Lempira, a heroic Lenca chieftain who led a major uprising against the Spanish invasion of what is now Honduras in the 1530s. Meaning "Lord of the Mountains" in the Lenca language, Lempira united historically rival tribes to form a formidable army, reportedly numbering around 30,000 warriors, operating from a fortified stronghold at Peñol de Cerquín. For months, his forces successfully resisted the Spanish troops led by captains like Alonso de Cáceres, threatening the very existence of the nascent Spanish colony. Historical accounts differ on his final moments, but the most cited version claims he was assassinated by a Spanish soldier under the pretense of a peace negotiation around 1537 or 1538. With his death, the organized indigenous resistance largely collapsed, allowing the Spanish to consolidate their dominion over the region, though Lempira remains an enduring national hero and symbol of resistance in Honduras, lending his name to the national currency, the Honduran Lempira. Tantilla lydia ANTÚNEZ-FONSECA, CASTRO, ESPAÑA, TOWNSEND & WILSON, 2020 The specific epithet lydia is an eponymous descriptor. It is a matronymic epithet, a proper name used as a name in apposition, honoring amphibian conservationist and environmental activist Dr. Lydia Allison Fucsko. Remarks: Dr. Lydia Allison Fucsko is a prominent amphibian conservationist and environmental activist based in Melbourne, Australia. Holding a Ph.D. in Environmental Education, her work promotes habitat conservation and species perpetuation through research and education. She is also an internationally published photographer, specializing in capturing images of amphibians, particularly frogs from southeastern Australia. Her dedication to the field has been recognized by the naming of a snake species, Tantilla lydia, in her honor in 2020. Notes: The spelling of the Latin transliteration from the Ancient Greek Ludia (Λυδα), meaning "beauty," "beautiful," "noble one," also fits the general appearance of the snake. Tantilla melanocephala (LINNAEUS, 1758) The specific epithet melanocephala is a color-based morphology descriptor of body parts. It is the feminine form of melanocephalus, a Latinized classical compound derived from the Greek words mélas (μέλας) meaning "black" (combining form in Latin: melano-,) and kephalḗ (κεφαλή) meaning "head" (Latin: cephalus), translating to "black-headed." It references the species' black head coloration distinguishing it from its brownish-gray body color. Grammatically, it is a nominative adjective in the first/second declension agreeing in gender and case with feminine Tantilla. It is used almost exclusively as a taxonomic epithet and thus not normally in inflected forms other than the nominative singular. Publication Quote: "Fuscus glaberrimus capite atro." It translates to, "Dark/dusky, very smooth, with a black head." Note that fufcus is not a known Latin word, though Linnaeus has used it several times for different taxa. It is believed to be equivalent to known Latin word fuscus meaning "dark," or "dusky."

It is a patronymic epithet, a proper name Latinized and put into the genitive case. The ending -i indicates that it honors a male individual. It is honoring American herpetologist, Dr. Kenneth Miyata. Remarks: Dr. Kenneth Miyata (1951–1983) was an accomplished American herpetologist whose promising career was tragically cut short. Despite his brief lifespan, he made significant contributions to the study of South American reptiles, particularly focusing on the ecology and systematics of snakes in the Amazon basin. His fieldwork provided valuable insights into species distribution and evolutionary relationships within tropical herpetofauna. He is honored in the onomastics of Tantilla for his important contributions to herpetology, especially concerning neotropical reptiles, which aligns with the genus's primary range. Tantilla moesta (GÜNTHER, 1863) The specific epithet moesta is a color-based morphology descriptor. It is the feminine form of the Latin adjective moestus ("sad," "mournful," or "grim.") Grammatically, it is a first/seconddeclension nominative singular adjective, agreeing in gender and case with the feminine genus Onomastic of Tantilla - Page | 19 Tantilla. The adjective moestus is a late formation as a perfect participle to moereō (an alternative form of maereō) meaning "to be sad," or "to be sad or mournful." The verb maereō in Classical Latin has neither a supine nor a perfect stem. It is likely referring to the dark, blackish color of the species (dorsal and ventral except for a yellow collar on the back of head and neck) resembling the attire of those attending mourning processions such as a funeral. Publication Quote: "Entirely deep black, with a broad yellow collar extending over the hind part of the occipitals; laterally; to the eyes; and below, over the whole chin and throat." Tantilla moesta, Blackbelly Centipede Snake - Solidaridad, Quintana Roo, Mexico - Pedro E. Nahuat-Cervera https://www.inaturalist.org/people/pedro_nahuat Creative Commons License Tantilla nigra (BOULENGER, 1914) The specific epithet nigra is a color-based morphology descriptor. It is a nominative singular feminine form of Latin adjective for black [niger (m), nigra (f), nirum (n)]. The adjective follows the first and second declension patterns and it matches the feminine gender of the genus Tantilla. It is referring to the dominant black color of the species both on the dorsal and ventral side of the species. Publication Quote: "Black above and beneath." Tantilla nigriceps KENNICOTT, 1860 The species epithet nigriceps is a color-based morphology descriptor referring to a body part. It is a compound Latin adjective meaning "lack-headed," formed from niger ("black,") and ceps, a Onomastic of Tantilla - Page | 20 combining form meaning "-headed," derived from the same root as caput ("head.") In Latin compounds, -ceps functions as an indeclinable combining element, so nigriceps is grammatically a third-declension one-termination compound adjective, remaining the same across masculine, feminine, and neuter nominative singular. The epithet refers directly to the distinctly deep black coloration of the head and anterior neck region. Publication Quote: "Crown as far as behind the occipitals deep black; no indication of a postoccipital black ring." Tantilla nigriceps, Plains Black-headed Snake - Midland County, Texas - Michael Price https://www.inaturalist.org/people/wild-about-texas Creative Commons License Tantilla oaxacae WILSON & MEYER, 1971 The species epithet oaxacae is a geography-based toponymic descriptor of a broader region than the specific type locality. It is the Latin genitive singular form of the place name Oaxaca, meaning "of Oaxaca," or "from Oaxaca." In zoological Latin, unaltered place names of non-Latin origin are commonly treated as first-declension feminine nouns for the purpose of forming genitives, hence Oaxaca becomes Oaxacae. The epithet refers to the species’ association with the Mexican state of Oaxaca as a broad geographic region rather than only the exact type locality. The type specimen was collected at "Santo Tomás Teipan, Oaxaca, Mexico," but the authors intended the epithet to reflect the species’ regional provenance within Oaxaca as a whole. Onomastic of Tantilla - Page | 21 Grammatically, oaxacae is a genitive singular noun used attributively, functioning as an uninflected epithet in apposition to the feminine genus Tantilla. Tantilla olympia TOWNSEND, WILSON, MEDINA-FLORES & HERRERA-B, 2013 The species epithet olympia is a narrative-based toponymic noun in apposition referencing a mythological deity. It is the feminine nominative singular form of olympia, a New Latin feminization of the classical Latin noun olympus ("Mount Olympus,") itself derived from Ancient Greek Ólympos (Όλυμπος) with the same meaning. In classical Latin, olympus is a second-declension masculine noun, but for zoological purposes the authors adopted the firstdeclension feminine form olympia, a standard Latinizing strategy when adapting a non-feminine noun to pair more harmoniously with a feminine genus name. As a noun in apposition, olympia remains grammatically invariable regardless of the gender of Tantilla. The holotype of T. olympia was collected by Paul House and Hermes Vega Rodríguez. Instead of creating a double patronym or choosing one collector over the other, the authors constructed a single symbolic motif, "House of Hermes," by blending House’s surname with Vega Rodríguez’s first name. Hermes, in Greek mythology, is one of the Twelve Olympian gods, renowned for his ability to move freely between the realms of the living and the dead. This mythological trait parallels the natural history of T. olympia, a semi-fossorial species that routinely transitions between surface leaf litter and subterranean microhabitats. The symbolism is further reinforced by geography: the species is native to the Cordillera de Nombre de Dios ("Name of God Mountain Range,") a landscape whose name already invokes divine association. The epithet olympia forms a multilayered narrative, honoring collectors, reflecting behavior, and echoing the cultural meaning embedded in the mountains from which the species was described. Mythology Note: Hermes (Ἑρμῆς) is the winged herald and messenger of the Olympian gods, renowned for his speed, cunning, and ability to move freely across the boundaries between the mortal, divine, and underworld realms. As the son of Zeus and Maia, he holds numerous portfolios, serving as the god of boundaries, travelers, roads, commerce, trade, athletes, eloquence, and invention. He is often characterized as a divine trickster, exemplified by his birthday theft of Apollo's cattle. Crucially, he is the psychopomp, the conductor responsible for guiding the souls of the dead to the afterlife. His most famous symbols include the caduceus (winged staff) and the talaria (winged sandals). He is identified with the Roman god Mercury. Tantilla oolitica TELFORD, 1966 The species epithet oolitica is a narrative-based toponymic descriptor. It is the feminine nominative singular form of the (Neo-)Latin adjective ooliticus meaning "of the oolite stone," The term oolite is a hybrid formation of Ancient Greek ōon (ᾠόν) meaning "egg," and Latin suffix -lite, or Greek lithos (λθος) meaning "stone." Oolite refers to a limestone composed of small, spherical, egg-like grains called ooids, giving the rock a distinctive appearance. Thus, Tantilla oolitica literally means "the Tantilla of the oolite stone," which effectively links the snake's restricted geographical range in Dade and Monroe counties, Florida, where the type specimen was collected, to its unique limestone bedrock. Grammatically, it is a first/seconddeclension three-termination nominative singular adjective and here agrees in gender and case with the feminine genus Tantilla. Publication Quote: "I designate the distinctive species of Tantilla restricted to Dade and Monroe counties, Florida, after its association with the dominant geological formation of the area, the Miami oolite." Onomastic of Tantilla - Page | 22 Remarks: The Miami oolite, now formally called Miami Limestone, is a major geological formation underlying much of South Florida. It forms the Atlantic Coastal Ridge and the land east of Everglades National Park and occurs in both Miami-Dade and Monroe counties, including beneath Florida Bay and the lower Florida Keys. It developed during the Pleistocene (c. 130 ka) during a warm, high-sea-level interval, when shallow marine conditions facilitated the formation of ooids—tiny carbonate grains that later lithified into an oolitic grainstone. The porous structure of this limestone is critical to South Florida hydrology, influencing aquifers and water movement across the Everglades. Pine rockland habitats grow on exposed oolitic ridges. The formation has two principal facies: the oolitic facies of the Coastal Ridge and the bryozoan facies to the west in the Everglades. Tantilla oolitica, Rim Rock Crowned Snake - Key Largo, Florida - AJ_Explorers https://www.inaturalist.org/people/aj_explorers Creative Commons License Tantilla palamala ESQUEDA, ROJAS-RUNJAIC, CORREA, ORTIZ, GUERRERO, JIMÉNEZ, BAZÓ, MORENO-PÉREZ, AGUILAR & URRA, 2025 The species epithet palamala is a pattern-based morphology descriptor. It is the feminine nominative singular New Latin form palamālā with literal meaning of "wing-shaped." This epithet is designated by the authors as a derived adjective from the Latin words palam, meaning "in the presence of," or "openly," and āla, meaning "wing". The name is intended to refer to a visible character in the snake's morphology: the lateral margins of the rostral scale in dorsal view, which resemble a "gull’s wing," that is "open and forming a V with a >90° obtuse angle". Onomastic of Tantilla - Page | 23 In this form, grammatically, it functions as a first/second-declension, three-termination adjective agreeing in case and gender with feminine genus Tantilla. Publication Quote" "The specific name is a derived adjective from the Latin words "palam," meaning in the presence of, openly and "ala," meaning wing to refer to a visible character in relation to the lateral margins of the rostral in dorsal view, that resemble a gull’s wing, that is, open and forming a V with a >90° obtuse angle and where the internasals tend to be laterally contracted." Grammar Notes: While we honor the authors' selection of the term as a derived adjective, (ICZN Article 31.2.1), the epithet is considered a New Latin coinage. The formation, which involves compounding the indeclinable adverb palam ("openly," or "visibly") with the first declension noun āla ("wing,") is non-standard in Classical Latin grammar. In my opinion, the resulting term is most logically analyzed as an indeclinable noun in apposition (e.g., Tantilla palamālā). Treating it as such avoids forcing this unique, descriptive compound into a Classical Latin adjectival declension for which it was not properly formed, thus providing a more accurate grammatical reflection of its construction. Tantilla petersi WILSON, 1979 The specific epithet petersi is an eponymous descriptor. It is a patronymic epithet, a proper name Latinized and put into the genitive case. The ending -i indicates that it honors a male individual. It honors American herpetologist, James A. Peters specializing on South American reptiles Remarks: James A. Peters (1922–1972) was an American herpetologist who made significant contributions to the taxonomy and systematics of reptiles and amphibians, often focusing on South American fauna. He was particularly active in the mid-20th century, contributing to the scientific descriptions and classifications of many tropical species. Peters held positions at institutions like the United States National Museum (now the Smithsonian National Museum of Natural History). His meticulous taxonomic work is likely why he is honored in the onomastics of Tantilla, recognizing his foundational efforts in classifying the diverse snake groups to which these species belong. Tantilla planiceps (BLAINVILLE, 1835) The species epithet planiceps is a morphology-based descriptor of body parts. It is a compound Latin adjective in masculine nominative singular form. It is derived from plānus ("flat") with - ceps, a derivative of caput ("head"), yielding "flat-headed." The term evokes a distinctive cranial morphology, referring to head shape of cranial form which is rather flat in comparison to most other Tantilla species. Grammatically, it is a third-declension one-termination nominative adjective, agreeing in gender and case with the feminine genus Tantilla. Publication Quote: "... tête petite, trcs-dcprimée, peu distincte, à museau court et elliptique ..." It translates to, "... small, very flat, indistinct head with a short, elliptical snout ..." Onomastic of Tantilla - Page | 24 Tantilla planiceps, Western Black-headed Snake - Mt Wilson, Los Angeles County, California - Tom Mills https://www.inaturalist.org/people/tmills Creative Commons License Tantilla psittaca MCCRANIE, 2011 The species epithet is a narrative-based toponymic noun in apposition. It is the feminine nominative singular form of psittaca, a New Latin feminization of the classical Latin noun psittacus ("parrot,") itself derived from Ancient Greek psittakós (ψιττακός) with the same meaning. In classical Latin, psittacus is a second-declension masculine noun ("a parrot"). For use as a zoological epithet, McCranie employed the feminine first-declension form psittaca, a common Latinizing strategy when adapting a non-feminine noun to agree stylistically with a feminine genus name or to produce a smoother epithet. As a noun in apposition, psittaca remains grammatically uninflected regardless of the gender of Tantilla. The epithet refers to the type locality of “Rawa (also sometimes spelled Rauha) Kiamp,” a Miskito place-name that translates as "Parrot Camp" in English. Thus, the name encodes the narrative of the species’ origin from a place whose indigenous name itself refers to parrots. Publication Quote: "The name psittaca is from the Latin psittacus and means parrot. The name alludes to the type locality Rawa (also sometimes spelled Rauha) Kiamp, in native language Miskito to Parrot Camp in English." Remarks: The Miskito (Miskitu) are an Indigenous people of the eastern Honduran and Nicaraguan Caribbean lowlands. Their language, also called Miskito, is a Misumalpan language, and many geographic names in northeastern Honduras derive from it. The type locality Rawa/Rauha Kiamp lies within traditional Miskito territory; although its literal meaning in Miskito is not provided by McCranie, its established English translation is "Parrot Camp." Thus, the epithet psittaca indirectly reflects both the Indigenous toponym and the cultural–geographic setting in which the species was discovered. Onomastic of Tantilla - Page | 25 Tantilla relicta TELFORD, 1966 The species epithet relicta is a distribution-based descriptive adjective referring to a biogeographic relict. It is the feminine nominative singular form of the Latin participle relictus, meaning "left behind," "remaining," or "surviving as a remnant," itself the perfect passive participle of relinquō ("to abandon," or "to leave behind.") The name reflects the biogeographical interpretation that the species represents a Pleistocene relict, persisting on ancient elevated landforms formed during fluctuations in sea level. Grammatically, relicta is a first/seconddeclension adjective of three-termination, used here in the feminine nominative singular to agree with feminine genus Tantilla. Publication Quote: "In recognition of its probable origin during fluctuations of Pleistocene sea levels, I designate the populations of Tantilla within peninsular Florida south of the Suwannee River and north of Dade County and the outlet of the Peace River into the Gulf of Mexico as Tantilla relicta." Grammar Notes: The perfect passive participle relictus derives from an older Indo-European root lic- ("to leave"). Latin introduces a nasal infix in the present stem (relinquin relinquere), but this infix disappears in the perfect system (relictum, relictus). This explains the apparent stem change between relinquō and its participial derivative relictus. Geological Note: The interpretation of Tantilla relicta as a Pleistocene relict is consistent with Florida biogeography. Much of peninsular Florida consists of ancient marine terraces formed when sea levels were higher during interglacial periods. As sea levels dropped, these highelevation ridges became isolated "islands" of xeric habitat. Species specialized for sandhill and scrub environments, including Tantilla relicta, remained restricted to these elevated Pleistoceneage formations. The subspecies Tantilla relicta pamlico is specifically named for the Pamlico Terrace, one of the youngest Pleistocene marine terraces formed when sea levels were approximately 8 m (25 ft) higher than today. Onomastic of Tantilla - Page | 32 as the authors' grammatical choice, though non-standard, but is the final and correct designation for the name. It is the authors' nomenclatural act. Tantilla striata DUNN, 1928 The species epithet striata is a pattern-based morphology descriptor. It is the feminine nominative singular form of the Latin adjective striātus, the perfect passive participle of the verb striō ("to make a groove," or "to score with lines.") The participial adjective striātus means "furrowed," "grooved," or, in zoological usage, "striped, or "lined," with the suffix -ātus denoting "provided with," or "characterized by." Grammatically, striata is a first/second-declension, threetermination, nominative singular adjective, here agreeing in gender and case with the feminine genus Tantilla. In taxonomic contexts, striatus and its feminine form striata often refer to species exhibiting longitudinal lines or stripes. The epithet here references the snake’s overall striped appearance; Dunn explicitly described the species as possessing "three light stripes." Tantilla supracincta (PETERS, 1863) The species epithet supracincta is a pattern-based morphology descriptor. It is the feminine form of the Latin adjective supracīnctus, a compound formed from the prefix supra- ("over,") from the preposition suprā (as related to location: "above," "on the top," "on the upper side,") and cīnctus ("belted," or "banded,") itself perfect passive participle (third conjugation verb cingere meaning "to gird," "to surround," or "to encircle,") literally meaning "belted above," "having bands on the upper side." The epithet refers to the species’ distinctive transverse head bands: a brownish-yellow band across the snout behind the nostrils, a similar spot on the fifth supralabial and adjacent scale edges, and another transverse band immediately behind the parietals. Grammatically, supracincta is a nominative, feminine first/second-declension, three-termination adjective, agreeing in gender and case with the feminine genus Tantilla. Publication Quote: "Kopf oben schwarz, mit einer braungelben Querbinde über der Schnauze hinter den Nasenlöchern, einen ebenso gefärbten Fleck auf dem fünften Supralabiale und den Rändern der angrenzenden Schilder, und einer Querbinde hinter den Parietalia, welche in die schmutzig gelbe Unterseite übergeht..." It translates as, "The head is black on top, with a brownish-yellow transverse band across the snout behind the nostrils, a similarly colored spot on the fifth supralabial scale and the edges of the adjacent scales, and a transverse band behind the parietal scales, which merges into the dirty yellow underside..." Onomastic of Tantilla - Page | 33 Tantilla supracincta, Banded Centipede Snake - Sube y Baja, Ecuador - Vilmer Herrera https://www.inaturalist.org/people/lacrespa Creative Commons License Tantilla taeniata BOCOURT, 1883 The species epithet taeniata is a pattern-based morphology descriptor. It is the feminine nominative singular form of the Latin adjective taeniātus meaning "striped," or "having stripes," derived from the Latin noun taenia ("ribbon," "stripe," or "band,") combined with adjectival suffix -ātus which denotes "provided with," or "characterized by." The epithet refers to the species’ dorsal striping, specifically the three yellowish stripes running from the neck to the tail. Grammatically, it is a first/second-declension nominative singular adjective, agreeing in gender and case with feminine genus Tantilla. Publication Quote: "Le corps, d’un fauve bistré, est parcouru dans sa longueur, jusqu’à l’extrémité de la queue, par trois lisérés de couleur jaunâtre, dont la largeur égale la moitié des intervalles les séparant entre eux." Translated as, "The body, of a brownish-tawny color, is traversed along its length, to the tip of the tail, by three yellowish stripes, whose width is equal to half the distance separating them." Remarks: This epithet exemplifies descriptive Latin formation used to capture clear morphological traits. The distinct dorsal banding is diagnostic, and the name directly encodes a Onomastic of Tantilla - Page | 34 visible character of taxonomic value. Such pattern-based adjectives are common when a species’ phenotypic features, especially stripes or coloration, serve as important identifiers. Tantilla taeniata, Central American Centipede Snake - Usulután, El Salvador - Carlos Funes https://www.inaturalist.org/people/carlosfunes Creative Commons License Tantilla tayrae WILSON, 1983 The specific epithet tayrae is an eponymous descriptor. It is a patronymic epithet, a proper name Latinized and put into the genitive case. The ending -ae indicates that it honors a female individual. It honors Tayra Barbara Wilson, author’s younger daughter (10 years old at the time of the snake’s description.) Tantilla tecta CAMPBELL & SMITH, 1997 The species epithet tecta is a narrative-based descriptor. It is the feminine nominative singular form of the Latin adjective tectus meaning "covered," "hidden," 'secret," or "concealed." It is the perfect passive participle of the Latin verb tegō ("to cover," "to hide," or "to shelter.") Grammatically, it is a first/second-declension three-termination nominative singular adjective and in here agrees in gender and case with the feminine genus Tantilla. The epithet refers to the fact that this species remained unnoticed and undetected for many years at a region that had been intensively studied by herpetologists Onomastic of Tantilla - Page | 35 Publication Quote: "...The trivial name is derived from the Latin tectus, meaning concealed or secret, in allusion to the ability of this species to escape detection despite many years of field work in the region..." Remarks: The narrative-based category is a recently added classification within etymological typology. It applies to epithets that convey a story about the species, an account, circumstance, or narrative context, rather than a straightforward reference to morphology, coloration, geography, or an eponym. A narrative epithet may still overlap with other categories, but when the narrative element is the primary motivation for the name, it is categorized as narrative. Examples of other snake taxa named for having been long overlooked or concealed include Bothriechis nubestris, Calamaria abstrusa, Dipsas aparatiritos, Geophis tectus, and Tropidophis greenwayi lanthanus. Tantilla tjiasmantoi KOCH & VENEGAS, 2016 The specific epithet tjiasmantoi is an eponymous descriptor. It is a patronymic epithet, a proper name Latinized and put into the genitive case. The ending -i indicates that it honors a male individual. It honors Wewin Tjiasmanto (Indonesia) in recognition of his support of nature conservation and taxonomic research. Remarks: Wewin Tjiasmanto is recognized for his significant role in supporting nature conservation and taxonomic research, particularly through his involvement with the BIOPAT initiative from Indonesia. BIOPAT is known for facilitating the connection between biological research and private sector funding, often involving the collection of bioprospecting access fees which are then channeled back into biodiversity research and conservation efforts in the originating country. His support ensures that scientific endeavors, such as the description of new reptile species like those in Tantilla, receive necessary financial backing for fieldwork and study. Tantilla trilineata (PETERS, 1880) The species epithet trilineata is a is a pattern-based morphology descriptor. It is a feminine form of the Latin adjective trilineātus meaning "three-lined," or "marked with three lines." It is formed from the prefix tri- ("three,") and the participial adjective lineātus ("lined,"), which itself derives from the noun linea ("line," or "stripe,") and the adjectival suffix -atus, meaning "provided with," or "having." The epithet refers to the snake's distinctive three dark-bordered yellow longitudinal stripes running along the body of the species. Grammatically, it is a first/second-declension nominative singular adjective, agreeing in gender and case with the feminine genus Tantilla. Publication Quote: "Drei gelbe dunkel eingefasste Längslinien, die mittlere längst dem Rückgrat, jede seitliche auf der drittletzten Schuppenreihe verlaufend." Translated as, "Three yellow, dark-bordered longitudinal lines, the middle one running along the spine, each lateral one along the third-to-last row of scales." Tantilla triseriata SMITH & SMITH, 1951 The species epithet triseriata is a pattern-based morphology descriptor. It is the feminine form of the Latin adjective triseriātus, formed from the numerical prefix tri-, derived from Latin trēs ("three,") and the participial adjective seriātus ("arranged in a row/series,") itself derived from seriēs ("row," or "succession,") with the suffix -ātus indicating "provided with," or "characterized by." Combined, triseriātus literally means "having three serial rows," or "provided with three rows/series." The name refers to three light yellow longitudinal stripes on the dorsum and the flanks of the species. Grammatically, triseriata is a singular, nominative, Onomastic of Tantilla - Page | 36 feminine first/second-declension adjective, agreeing in gender and case with the feminine genus Tantilla. Publication Quote: "Ground color of body rich chestnut brown dorsally with three light yellow longitudinal stripes; middorsal stripe beginning 1.5 scale lengths behind nuchal collar, at which point it is one scale wide; seven scale lengths behind collar middorsal stripe widens, covering inner halves of paravertebral scale rows, continuing almost to tip of tail; lateral stripes beginning three scale lengths behind seventh supralabials, 1.5 scale lengths behind nuchal collar, occupying adjacent halves of third and fourth scale rows, continuing almost to tip of tail; light stripes on body approximately half the width of dark background; middorsal stripe, except at extreme anterior end, slightly wider than laterals;" Grammar Notes: The long publication excerpt is important because it clarifies why the authors used seriātus ("arranged in rows/series") rather than lineātus ("lined," "provided with continuous lines.") The original description does not depict three continuous, perfectly parallel lines. Instead, the markings represent three longitudinal series of pale scales whose points of origin, widths, and continuity change along the body: (1) the middorsal series begins ~1.5 scale lengths behind the nuchal collar and later widens to cover the inner halves of the paravertebral rows, (2) the lateral series begin farther posteriorly (three scale lengths behind the seventh supralabial,) (3) the series vary in width and are not perfectly continuous. Because the pale markings correspond to rows of scales rather than uniform lineae, the epithet triseriata ("with three rows/series") is the grammatically and morphologically precise choice. Tantilla tritaeniata SMITH & WILLIAMS, 1966 The species epithet tritaeniata is a pattern-based morphology descriptor. It is the feminine form of the Latin adjective tritaeniātus, formed from the numerical prefix tri-, derived from Latin trēs ("three,") and the participial adjective taeniātus ("striped," “banded,” or "having stripes,") itself derived from the Latin noun taenia ("ribbon," "stripe," or "band,") with the suffix -ātus conveys "provided with," or "characterized by." Together. tritaeniata translates to "three-striped," or "having three stripes." The name refers to three thin, pale, longitudinal stripes, each narrowly edged in black, running along the dorsum and flanks of the species. Grammatically, tritaeniata is a singular, nominative, feminine first/second-declension adjective, agreeing in gender and case with the feminine genus Tantilla. Publication Quote: "Three black-edged light stripes on body, beginning one scale length or less from collar, all at full width at their anterior extremities; median light line one and two half scale rows wide; lateral light lines on adjacent halves of 3rd and 4th scale rows; vertebral stripe visible throughout most of length of tail, lateral stripes disappearing on base of tail within 4 scale lengths of anus. Dark areas between light lines, and below lateral light line, sharpy delimited, black-edged; lateral dark stripe involving 2nd scale row and adjacent halves, the dorsolateral dark stripes the 5th and 6th scale rows and adjacent halves; venter and lower half of 1st scale row unmarked anteriorly, but the lateral dark stripe descending posteriorly to involve the extreme tips of the ventrals, although actually not all of the lower edges of the scales in the first row of dorsals." 2nd Publication Quote: "T. tritaeniata clearly belongs to the section of the genus that includes flavilineata, jani, striata and triseriata in Mexico, taeniata in Guatemala, trilineata from an unknown locality, and perhaps reticulata and virgata in Costa Rica and Panama. All are lightlined and lack the dark median stripe characteristic of the melanocephala group."

It is Latin adjective vermifōrmis meaning "vermiform," or "worm-shaped," derived from the Latin nouns vermis ("worm,") and forma ("form," "figure," or "shape,") with the compound adjectival ending -formis ("having the form of," or "shaped like.") Grammatically, vermiformis is a thirddeclension two-termination (vermiformis for masculine/feminine; vermiforme for neuter) adjective agreeing in gender and case with the feminine genus Tantilla. As with most Latin - formis adjectives used as zoological epithets, the word appears the word appears almost exclusively in the nominative singular and is rarely encountered in inflected forms outside taxonomic contexts. The epithet refers directly to the snake’s extremely slender, uniform body shape, which gives it a worm-like appearance. Publication Quote: "Body very slender, rounded, and about the same thickness from the head to the tail." Onomastic of Tantilla - Page | 38 Tantilla vermiformis, Hallowell's Centipede Snake - Provincia de Guanacaste, Hacienda Naranjo, Costa Rica - Marcos Alvarez-Garita https://www.inaturalist.org/people/marcos_alvagar Creative Commons License Tantilla vulcani CAMPBELL, 1998 The species epithet vulcani is an eponymous descriptor in allusion to the habitat. It is a patronymic epithet, a proper name Latinized and put into the genitive case. The ending -i indicates that it honors a male individual. It is the genitive singular form of the Latin noun Vulcanus, meaning Vulcan, the Roman God of fire. According to Campbell (1998) the name was chosen "in allusion to the habitat of this species on the Pacific versant of Guatemala which is dominated by a series of spectacular Quaternary volcanoes, some still active." The specific type locality is "Finca El Carmen, Quezaltenango, Guatemala." Geography Notes: The Pacific versant of Guatemala is a geographically distinct and active region dominated by the Sierra Madre de Chiapas Mountain range, which features the prominent Volcanic Arc of Central America. This arc, often referred to as the Pacific Volcanic Belt, is characterized by a chain of spectacular Quaternary volcanoes, many of which are still active or Onomastic of Tantilla - Page | 39 dormant. Key stratovolcanoes like Volcán Tajumulco (the highest peak in Central America), Volcán Santa María, Volcán Atitlán, Volcán de Fuego, and Volcán Pacaya define the landscape and form a high-elevation barrier separating the Pacific coastal plain from the interior highlands. This region, extending from the Mexican border southeastward, is known for its steep slopes, high rainfall on the lower slopes, and fertile volcanic soils, making it ecologically rich and agriculturally important, especially for coffee cultivation. Tantilla wilcoxi STEJNEGER, 1902 The specific epithet wilcoxi is an eponymous descriptor. It is a patronymic epithet, a proper name Latinized and put into the genitive case. The ending -i indicates that it honors a male individual. It honors Timothy Erastus Wilcox, a surgeon who also collected the holotype. Remarks: Timothy Erastus Wilcox (1840–1932) was a United States Army surgeon and enthusiastic naturalist. He was a graduate of the College of Physicians and Surgeons of New York and served as a surgeon in the U.S. Army for decades, with a posting at Fort Boise in the late 1800s, where he was also known as Boise's first resident botanist. His diverse contributions to natural history in the American frontier are what led to him being commemorated in the scientific name of the species.

It is a Latinized feminine adjectival form derived from the non-Latin noun Yaqui (people). It is (presumably) referring to the indigenous inhabitant of the type locality, the Yaqui people (see Remarks). The -a or -ia at the end of the name indicates a feminine adjective. Grammatically, it is a first/second-declension nominative singular adjective, agreeing in gender and case with the feminine genus Tantilla. The specific type locality is "Guasaremos, Rio Mayo, Chihuahua, Mexico." Remarks: There is a clear conflict between the name's meaning and the type locality's indigenous association. While the epithet indicates naming after the indigenous people living in type locality, that does not match the historical facts about traditional homeland of Yaqui people. The type locality of the snake specimen is "Guasaremos, Río Mayo, Chihuahua" which is a traditional homeland of the Warihio (Guarijío) people noy Yaquis. McDiarmid (1977) attempted to resolve the conflict by stating, "... refers to the Yaqui Indians, whose influence was often felt in the area of the type locality," (fide Reptile Database). So, either Smith intended to name the species after Yaqui people with the knowledge that they did not live in the region, or he mistakenly assumed the region was the traditional place for Yaquis. Subspecies Tantilla relicta neilli TELFORD 1966 The subspecies epithet neilli is an eponymous descriptor. It is a patronymic epithet, a proper name Latinized and put into the genitive case. The ending -i indicates that it is named after a male individual. It is honoring American herpetologist Wilfred Trammell Neill Jr., in recognition of his significant contributions to the field of herpetology. Remarks: Wilfred Trammell Neill Jr. (1922–2001) was an American herpetologist who spent his career studying the amphibians and reptiles of the southeastern United States, the region where Tantilla relicta is found. Neill was also an expert on the natural history and ethnobiology of the Florida area and published numerous papers, including descriptions of new species. He made notable contributions to the natural history and taxonomy of this fauna, leading to the naming of this subspecies in his honor. Onomastic of Tantilla - Page | 41 Tantilla relicta neilli, Central Florida Crowned Snake - Clyattville, Georgia - gshrum https://www.inaturalist.org/people/gshrum Creative Commons License Tantilla relicta pamlica TELFORD 1966 The subspecies epithet pamlica is a geography-based descriptor of a broader region than the specific type locality. It is a Latinized feminine adjectival form derived from the non-Latin noun Pamlico (terrace). Grammatically, it is a first/second-declension nominative singular adjective, agreeing in gender and case with the feminine genus Tantilla. The specific type locality is "approximately 1 mile south of Boynton Beach, Palm Beach County, Florida." The Tantilla relicta pamlica is primarily found in the northern and central parts of the Florida peninsula, an area that broadly encompasses and is heavily influenced by the geological feature known as the Pamlico Terrace. Remarks: The Pamlico Terrace is the name of a marine terrace (an ancient, nearly level plain formed by sea level when it was higher) that extends along much of the Atlantic Coastal Plain, including Florida. This geological feature is generally found at a low elevation, typically between 25 and 35 feet (7.6 to 10.7 meters) above sea level in Florida, and is composed of marine Pleistocene deposits, like Pamlico sand. The type locality is part of the modern land surface that sits on top of this Pamlico and other ancient marine terraces. The Pamlico Terrace is generally defined by an elevation of about 25 to 35 feet above current sea level.
