We present an annotated catalogue for the tribe Incini (Coleoptera: Scarabaeidae: Cetoniinae) including references to all taxonomic and nomenclatural acts, clarifying the spelling of names, providing type depositories and occurrence records for the species. The spelling of Golinca davisii (Waterhouse, 1877) is fi xed, and the incorrect subsequent spelling Pantodinus klugi Burmeister, 1847 is preserved. A comprehensive list of all valid names in Incini is provided. Furthermore, we describe the third species in the genus Archedinus Morón & Krikken, 1990, and fi rst one known from outside of Mexico, A. antoshkai Seidel & Arriaga-Varela sp. nov. from Cerro las Minas, the highest mountain in Honduras. We provide an updated determination key for the species of Archedinus. The new species is compared with Archedinus howdeni Morón & Vaz-de-Mello, 2007, the most similar species in terms of genital and habitus morphology. An updated key to identifi cation of males of Archedinus is provided. Key words.

Accepted: 1st August 2018 Published online: 10th September 2018 Introduction Incini is a Neotropical tribe of fl ower chafers (Coleoptera: Scarabaeidae: Cetoniinae). Previously, this group of beetles has been treated as a subtribe Incaina in the subfamily Trichiinae (e.g., MORÓN & KRIKKEN 1990; MORÓN & VAZ-DE-MELLO 2007; SMITH 2006). SMITH et al. (2006) indicated the need for elevation of the subtribe to tribal level, since the historical concept of the tribe Trichiini was paraphyletic based on their preliminary molecular data. Agreeing with that, more recent works treat this group as a tribe in the subfamily Cetoniinae based on morphological and molecular phylogenetic analyses (e.g., MICÓ et al. 2008, ŠÍPEK et al. 2016). BOUCHARD et al. (2011) corrected the stem and spelling of the family group name to Incand Incini. The taxonomic history of the species and genera in the tribe is complex. The spelling of species names, authors and year of publication of species have been cited differently by cataloguers, taxonomists, and ecologists. The lack of a complete and comprehensive work dealing with the nomenclature in this tribe is an obstacle for taxonomists aiming to continue research on Incini. Five Incini genera have been reported from Mexico to Argentina (Fig. 6): Archedinus Morón & Krikken, 1990 (Figs 1–3, 5A–B), Coelocratus Burmeister, 1842 (Figs 5C–D), Inca LePeletier & Serville, 1828 (Figs 5E–G), Golinca Thomson, 1878 (Figs 5H–J) and Pantodinus Burmeister, 1847 (Figs 5K–M). The genus Archedinus was described by MORÓN & KRIKKEN (1990) in order to include a single species, A. relictus 2018 58(2): 389-405 doi: 10.2478/aemnp-2018-0031 Seidel.indd 389 10.9.2018 15:36:27 SEIDEL et al.: Catalogue of Incini and description of a new Archedinus (Coleoptera: Scarabaeidae) 390 Morón & Krikken, 1 990 from Chiapas, Mexico. Archedinus is currently classifi ed within the tribe Incini, close to Pantodinus as a “relictual” representative with reduced sexual dimosphism. Males and females of A. relictus were described based on nine specimens collected in the cloud forest of El Triunfo in the Sierra Madre de Chiapas mountain range. Later, MORÓN & VAZ-DE-MELLO (2007) described a second species, A. howdeni from Chimalapas region in Oaxaca, Mexico based on four male specimens and expanded the generic defi nition of Archedinus. The position of Archedinus within the other Incini was tested based on a morphological phylogenetic analysis, where it was sister taxon of Pantodinus and, along this one, sister to the remaining Incini. Not much is known about the life history of the genus. Archedinus relictus was reported having “diurnal activity, living under forest litter and rotten logs in montane humid forests located at elevations going from 1000 to 1850m” (MORÓN & KRIKKEN 1990). Archedinus howdeni was found in “tropical subdeciduous forest at 1600 m” (MORÓN & VAZ-DE-MELLO 2007). Besides these two type localities in Mexico, no other faunistic records have been published. Therefore, the distribution range of Archedinus is very poorly known. In the present contribution we describe a third species recently collected in Honduras, showing that the genus is not solely endemic to Mexico and has a much larger distribution range than previously known. We update the generic diagnosis and the determination key based on the work of MORÓN & VAZ-DE-MELLO (2007). In addition, we present an annotated catalogue of the Incini aiming to resolve all the nomenclatural problems in the tribe. Material and methods Collections.

Seidel.indd 390 10.9.2018 15:36:28 Acta Entomologica Musei Nationalis Pragae, volume 58, number 2, 2018 391 Results Archedinus Morón & Krikken, 1990 Type species. Archedinus relictus Morón & Krikken, 1990: 76. Diagnosis. This genus is distinguished from other members of the tribe Incini by the following combination of characters: body length 17–27 mm, dorsal integument shiny, dark-brown to black; clypeal anterior margin sinuated, male with short clypeal horn or elevated clypeal margin lacking lateral or medial clypeal horns (present in Golinca, Inca and Pantodinus); eyes with strong supraocular ridges; male with antennal club longer than pedicel and funicle together, mentum with anterior margin sinuate or rounded; pronotum coarsely punctate, without posterior impression; anterior prosternal process projected, longer than procoxal length, elytra deeply striate without waxy surface; pterothoracic setae sparse; profemur with a preapical projection; protibia with 3 external teeth; mesoand metatibiae expanded, tridentate; aedeagus with parameres simple or bifurcate. Archedinus is most similar to Pantodinus due to the sinuate antero-ventral clypeal margin and the well marked elytral striae. However, Archedinus can be distiguished by the strong supraocular ridges, the prosternal process being longer than the procoxal anterior face, and by the sparse setae on the pterosterna (MORÓN & VAZ DE MELLO 2007). The third stage larva of A. relictus was diagnosed from other Incini (MORÓN 1995) by having mandibles without a stridulatory area; premolar area on left mandible with 2 teeth; dorsoepicranial setae absent; maxillary stridulatory area with 12 irregular, non-pointed teeth; last antennomere with 7–13 dorsal sensory spots; tarsal claws with 2 internal preapical setae; spiracle respiratory plates with irregular, ameboid “holes”; dorsal and ventral abdominal sclerites with long setae.

Profemur with a preapical, blade-like, dorsal projection, with rounded apex. Protibia with a wide inner basal notch. All tarsi robust, with large, sickle-shaped claws. Abdomen. Ventrites convex, almost glabrous, with sparse, small decumbent setae, fi nely punctate, punctures narrowly transverse; last ventrite with deeper, more rounded punctures on posterior margin which is slightly raised and briefl y emarginate at middle. Pygidium glabrous, shiny, with dense, fi ne micropunctures mixed with sparse, large, sometimes confl uent, round punctures, fi nely rugose toward basal angles; without waxy spots; posterior margin nearly rounded. Genitalia. Aedeagus with large basal piece, slightly convex; tectum shallowly concave; parameres elongate, sinuous in lateral view, with apical third bifurcate in apical third in dorsal view, apex rounded (Figs 3A–B). Female. Unknown. Differential diagnosis. Archedinus antoshkai is most similar to A. howdeni based on the emarginate clypeal projection, anterior prosternal process with rounded apex, and the apices of the parameres not being bifurcate. However, it can be distinguished from it by its smaller size (17.5 mm in A. antoshkai versus 25–27 mm in A. howdeni), the clypeal projection with anterior margin more strongly emarginate medially (Fig. 2A in A. antoshkai versus Fig. 2B,D in A. howdeni), in A. howdeni the frons is with an elongate, triangular depression (Figs 2A,C in A. antoshkai versus Fig. 2B in A. howdeni), the third antennomere is small, being as long as the fourth (Fig. 3F in A. antoshkai versus Fig. 3G in A. howdeni), the mentum is elongate with a rounded anterior margin (Fig. 3D in A. antoshkai versus Fig. 3E in A. howdeni), pronotum with coarser lateral margins (Figs 2C,E in A. antoshkai versus Figs 2D,F in A. howdeni) and the aedeagus with apices of the parameres simple, without a small lateral projection (Fig. 3A in A. antoshkai versus Fig. 3C in A. howdeni). Etymology. The new species is named after Anton Olegovich Kozlov (Moscow, Russia), who made the specimen available for study and generously donated the holotype to us. The name refers to the diminutive form of his fi rst name, “Antoshka”, used by friends; noun in apposition. Natural history. The species occurs in the highest mountain in Honduras in a tropical cloud forest at 2600 m elevation. Female specimens, immature stages, and life cycle are unknown. Distribution. Only known from the type locality: Cerro Las Minas in Celaque National Park, Lempira Department, Honduras.

Seidel.indd 394 10.9.2018 15:36:30 Acta Entomologica Musei Nationalis Pragae, volume 58, number 2, 2018 395 Catalogue of the tribe Incini Tribe Incini Burmeister, 1842 Incadae Burmeister, 1842: 704 [original spelling] Type genus. Inca LePeletier & Serville, 1828. Remarks. BOUCHARD et al. (2011) corrected the stem of the family group name from Incato Inc-, lacking an explanation for their action. As discussed below under the section Inca, Inca is a masculine genus name derived from Spanish. While creating family-group names BURMEISTER (e.g., 1842, 1844) removed a few fi nal letters from every genus name independently from their gender and added suffi xes such as -idae, -didae or -adae (e.g., Lomapteridae Burmeister, 1842 [from Lomaptera Gory & Percheron, 1833]; Macraspididae Burmeister, 1844 [from Macraspis MacLeay, 1819]; Lichniadae Burmeister, 1844 [from Lichnia Erichson, 1835]). Therefore, it can be securely assumed that the correct stem of Incadae Burmeister, 1842 is Incand Article 29.3.3. (ICZN 1999) is followed: “If a generic name is or ends in a word not Greek or Latin, or is an arbitrary combination of letters, the stem for the purposes of the Code is that adopted by the author who establishes the new family-group taxon, either the entire generic name (see Article 29.6), or the entire generic name with the ending elided, or the entire generic name with one or more appropriate linking letters incorporated in order to form a more euphonious family-group name”.

Distribution. According to GORY & PERCHERON (1833), Coelocratus rufi pennis is from Brazil, but they did not provide a more detailed locality, and BURMEISTER (1842) restricted it to northern Brazil. Actual specimens in the Burmeister collection (MLUH) are labelled as being from Cayenne (French Guiana) (Fig. 6).

As noted by MACLEAY (1838) the author of the species is GORY & PERCHERON (1833) and not Dupont as stated in GORY & PERCHERON (1833). DI IORIO (2013) overlooked the lectotype designation by RICCHIARDI (2002) and designated a lectotype in the Burmeister collection housed in the MACN. RICCHIARDI (2002) validly designated the lectotype based on one syntype of Inca rufi pennis housed in the MNHG collection. The syntype sent by Gory & Percheron to Burmeister in Argentina therefore has to be regarded as a paralectotype. Genus Golinca Thomson, 1878 Golinca Thomson, 1878: 31 [original description] Type species. Cetonia bifrons Olivier, 1789: 82 [by original designation]. Gender. Masculine. Species included. 4 species. Remarks. When describing Golinca, THOMSON (1878) did not state the gender of the genus name and as such it has not been subsequently established with the combination of specifi c epithets. We assume that Thomson derived Golinca from the generic names Goliathus and Inca, two genera of which Incini species were previously combined with. Therefore, the gender of the genus should be regarded as masculine, like in Inca (see above).

Female holotype in BMNH. Remarks. SCHENKLING (1922), while transferring Inca davisii Waterhouse, 1877 to the genus Golinca, misspelled the specifi c epithet as “davisi” lacking one “i”. This incorrect subsequent spelling has since been used by several authors (BERGÉ 1884, BLACKWELDER 1944, KRAJCIK 1999, MORÓN & VAZ-DE-MELLO 2007, VALOIS & SILVA 2015). Nevertheless, the correct spelling, G. davisii, remained in use (NAGAI 1994, RATCLIFFE et al. 2015, DE SOUZA SILVA et al. 2017). We follow Art. 33.3 (ICZN 1999) which states that “any subsequent spelling of a name different from the correct original spelling, other than a mandatory change or an emendation, is an “incorrect subsequent spelling”; it is not an available name”. Since both the correct and incorrect subsequent spellings were recently in use, the incorrect subsequent spelling is not in prevailing usage and cannot be preserved under Art. 33.3. The name to be used is Golinca davisii (Waterhouse, 1877). Golinca ishiharai Nagai, 1994 Golinca ishiharai Nagai, 1994: 243 [original combination] Types.

Genus Inca LePeletier & Serville, 1828 Inca LePeletier & Serville, 1828: 380 [original description] Ynca Chevrolat, 1833: unpaginated [unjustifi ed emendation] Type species. Cetonia ynca Weber, 1801 [subsequent designation by HOWDEN (1968: 12)] Gender. Masculine. Remarks. The authorship and date of publication of the name Inca has been the subject of confusion. BLACKWELDER (1944), MORÓN et al. (1997), KRAJCIK (1999) and RESTREPO-GIRALDO et al. (2003) erroneously attributed the authorship of Inca to “Serville (1825)”. BOUSQUET (2016) showed that the second livraison of the “Encyclopédie méthodique” containing pages 345 to 832 was published in December 1828. The authors of Inca are LEPELETIER & SERVILLE (1828) as stated on page 346 in the second livraison. KRAJCIK (1999) erroneously listed Ynca as a synonym to Inca and attributed authorship to GORY & PERCHERON Seidel.indd 396 10.9.2018 15:36:30 Acta Entomologica Musei Nationalis Pragae, volume 58, number 2, 2018 397 (1833). However, the name Ynca was introduced by CHEVROLAT (1833) as an unjustifi ed emendation and later used by LAPORTE (1840). LEPELETIER & SERVILLE (1828) did not explain the origin and gender of the genus name. Furthermore, the specifi c epithets associated with the genus in the original description are either gender neutral or can be either masculine or feminine. Since, LEPELETIER & SERVILLE (1828) changed the specifi c epithet “barbicorne” (neutral) to “barbicornis” (masculine and feminine), it is clear that they deemed the gender of the genus not to be neutral. The genus name Inca is derived from the Spanish noun “Inca” (masculine). According to the Diccionario de la Lengua Española (REAL ACADEMIA ESPAÑOLA 2014) the masculine noun “Inca” has three meanings: 1) sovereign who ruled the Inca Empire; 2) descendant of the Inca; 3) old gold coin of Peru. We follow Art. 30.2.1. (ICZN 1999), which states: “If a name reproduces exactly a noun having a gender in a modern European language (without having to be transliterated from a non-Latin alphabet into the Latin alphabet) it takes the gender of that noun.” Since these conditions are met in this case, the gender of the genus Inca is masculine. Furthermore, BURMEISTER (1842) considered the genus name to be masculine and therefore adapted previously feminine species epithets into the masculine form. The type species of the genus was not selected until HOWDEN (1968) designated Cetonia ynca Weber, 1801 as type species. HOWDEN (1968) thought that the original specifi c epithet spelling was “inca” not “ynca” and therefore designated the type species by tautonomy following Art. 68.4 (ICZN). Even though in this case the absolute tautonymy was not met, we follow Art. 69.1.1 (ICZN 1999), which states that: “in the absence of a prior type fi xation for a nominal genus or subgenus, an author is deemed to have designated one of the originally included nominal species as type species, if he or she states (for whatever reason, right or wrong) that it is the type or type species, or uses an equivalent term, and if it is clear that that author accepts it as the type species.” Therefore, the subsequent designation of Cetonia ynca as type species of Inca by HOWDEN (1968) is valid. Distribution. Known from Tamaulipas in Mexico through Central and South America to Paraguay and northern Argentina (Fig. 6). There are no records known to us from Venezuela, Guyana, and Suriname, but specimens collected in Trinidad and close to the Venezuela and Suriname borders indicate the genus might well be distributed in those countries.
