Research Article Abstract The Neotropical Clistopyga henryi species-group includes currently four described species. In this study, we describe two new species (C. peruandina Sääksjärvi & Pádua, sp. nov. and C. teresopolitana Pádua, sp. nov.) from the Peruvian Andes and Brazilian coastal rainforests. In addition, we provide information on the variation of C. carinata Bordera & Palacio and a key to species of the species-group. Key words: Biodiversity, Darwin wasps, Ephialtini, parasitoid wasps, rainforests, spiders Introduction Clistopyga Gravenhorst, 1829 is a moderately large Darwin wasp genus with 93 valid species (Bordera et al. 2016, 2019, 2025; Yu et al. 2016; Palacio et al. 2018, 2019; Bordera and Palacio 2019; Higa et al. 2024), the great majority of which are distributed in the Neotropical region, followed by the Nearctic, Palearctic, Oriental, and Afrotropical regions (Bordera et al. 2025). The biology of the genus remains poorly understood but existing evidence suggests that Clistopyga represents an evolutionary transition from idiobiont ectoparasitoid wasps that parasitize the silken cocoons of Lepidoptera (Gauld 1991; Gauld and Dubois 2002) to groups that lay eggs in the silken eggs sacs of spiders (Fritzén and Sääksjärvi 2016; Bordera et al. 2025), and ultimately to more derived species-groups functioning as koinobiont ectoparasitoids of active, mobile spiders (Nielsen 1929; Fitton et al. 1988; Wahl and Gauld 1998). Clistopyga is most closely related to Zaglyptus, and together with the Polysphincta group they form a unique lineage within Ephialtini, characterized by the use of spiders and their egg sacs as a resource for larval development (Gauld and Dubois 2002). Based on morphological characters, the genus has been divided into six species-groups which are all known to occur in the Neotropical region (Gauld 1991; Bordera et al. 2016, 2019, 2025; Palacio et al. 2018, 2019; Bordera and Palacio 2019).

Pádua et al.: New species of the Clistopyga henryi species-group from Brazil and Peru Gauld (1991) was the first to propose the C. henryi species-group to host a single species with a long and straight ovipositor (C. henryi Gauld, 1991). Palacio et al. (2019) later revised the species-group, described three new species (C. carinata Bordera & Palacio, C. declinata Palacio & Bordera, and C. teresitae Díaz, Palacio & Bordera) from Brazil, Colombia, and Venezuela and provided an additional diagnostic feature for the species-group. More recently, Bordera et al. (2025) synonymized the Afrotropical genus Afroanomalia Varga, 2018 with Clistopyga and, consequently, transferred A. pseudoclistopyga Varga, 2018 to Clistopyga (C. pseudoclistopyga (Varga, 2018)), recognizing it as part of the C. henryi species-group. Therefore, the genus-group currently contains five species, which are mainly characterized by occipital carina complete, not raised in a flange-like protuberance; fore leg with tibia swollen in their basal half; ovipositor straight or evenly down-curved at distal 0.4; upper valve with evenly tapered, without fine longitudinal rugulae (Varga 2018; Bordera et al. 2025). In this study, we describe two new species of C. henryi species-group, C. peruandina Sääksjärvi & Pádua, sp. nov. and C. teresopolitana Pádua, sp. nov.) from the Peruvian Andes and Brazilian coastal rainforests, respectively, as well as provide additional information on the morphological variation of the female C. carinata and a key for all the Neotropical and Afrotropical species of the genus. Material and methods The specimens analyzed in this study are deposited in the Departamento de Ecologia e Biologia Evolutiva, São Carlos, São Paulo, Brazil (DCBU), Invertebrate Collection of the Instituto Nacional de Pesquisas da Amazônia, Manaus, Brazil (INPA), Zoological Museum of the Universidade de São Paulo, São Paulo, São Paulo state, Brazil (MZUSP), Entomological Collection of the Universidade Federal do Espírito Santo, Vitória, Espírito Santo, Brazil (UFES), Museo de Historia Natural, Universidad Mayor de San Marcos, Lima, Peru (UNSM) and Zoological Museum of the University of Turku, Turku, Finland (ZMUT). The morphological terminology follows Broad et al. (2018) and the style of descriptions follows Palacio et al. (2019). The specimens were examined using a Leica EZ4 stereomicroscope (in INPA) and an Olympus SZX10 stereomicroscope (in ZMUT). Measurements were made through a WF10×/22 focusing eyepiece coupled with a 10 mm/100 division reticle and calibrated with a precision ruler. Digital images were taken using a Leica DFC450 digital camera attached to a Leica M205C stereomicroscope and combined by using the software Leica Application Suite v. 4.6 or Helicon Focus v. 5.3 Pro (in INPA), and using a Canon DS126461 digital camera attached to an Olympus SZX16 stereomicroscope and combined by using the software Zerene Stacker v. 1.04 (in ZMUT) and measurements were made using the software Leica LAS X. Drawings were digitally vectorized using the software Adobe Illustrator. In this study, the measurements and proportions between the structures are given as the value of the holotype or paratype [in brackets], followed by the minimum and the maximum number of variations if needed. [Brackets] were also used to add, supplement, or correct information on the specimen labels. The distribution maps were created using SimpleMappr online software (Shorthouse 2010). 25 ZooKeys 1260: 23–36 (2025), DOI: 10.3897/zookeys.1260.163690 Diego G.

Etymology. The specific name “teresopolitana” is an adjective referring to the type locality, Teresópolis, Rio de Janeiro, Brazil. The toponym, meaning “city of Teresa,” combines the personal name Teresa (of Greek origin) with the Greek word πόλις (pólis, “city”). Distribution. Brazil (Fig. 6). Remarks. Clistopyga teresopolitana sp. nov. resembles C. henryi Gauld, 1991 mainly by body coloration (reddish-orange in general), submetapleural carina not complete, and ovipositor straight, not decurved. However, it clearly differs from C. henryi by its shorter ovipositor (2.2× as long as the hind tibia, ovipositor 2.7–2.8× as long as hind tibia in C. henryi). Clistopyga carinata Bordera & Palacio, 2019 Figs 4, 6 Clistopyga carinata Bordera & Palacio, 2019: 105. Holotype: ♀, Brazil (AEIC). Diagnosis. According to Palacio et al. (2019), this species can be distinguished from all other species of C. henryi group by the combination of the following characteristics: 1) hind wing with distal abscissa of CU well pigmented; 2) metapleuron and propodeum reddish-orange; 3) submetapleural carina complete; 4) tergites II–VIII predominantly dark brown; 5) female with ovipositor evenly down curved at distal 0.4.
