Description

Four new genera are described to resolve the recent placement of non-congeneric species in Hapalopus Ausserer, 1875 and Thrixopelma Schmidt, 1994. Further taxonomic notes on Hapalopini are provided. Crypticarachne gen. nov. is described for the newly combined monotypic species Crypticarachne nadineae (Sherwood & Gabriel, 2022) comb. nov. Devicarina gen. nov. is described to house the newly combined species Devicarina akroa (Moeller, Galleti-Lima & Guadanucci, 2024) comb nov. (type species) and Devicarina guidonae (Moeller, Galleti-Lima & Guadanucci, 2024) comb. nov. which were clearly misplaced in Hapalopus. Ewok gen. nov. is described for six newly combined and two newly described species: Ewok aymara (Chamberlin, 1916) comb. nov., Ewok aycaramba sp. nov., Ewok christineae (Sherwood & Gabriel, 2024) comb. nov. (type species), Ewok cyaneolum (Schmidt, Friebolin & Friebolin, 2005) comb. nov., Ewok eliseanneae (Sherwood & Gabriel, 2024) comb. nov., Ewok kainae sp. nov., Ewok kimraykawsaki (Signorotto et al., 2025) comb. nov. and Ewok pruriens (Schmidt, 1998) comb. nov. Warmiru gen. nov. is described to accommodate the newly combined species Warmiru lagunas (Schmidt & Rudloff, 2010) comb. nov. and Warmiru longicolli (Schmidt, 2003) comb. nov. (type species). Thrixopelma peruvianum (Schmidt, 2007) syn. nov. is proposed as a junior synonym of Warmiru longicolli comb. nov. based on spermathecal morphology. Finally, Anqasha lima sp. nov. is described based on material from Peru in accordance with Article 13 of the International Code of Zoological Nomenclature. The recent misidentification of palpal bulb keels by Kaderka & Quispe- Colca (2025) is corrected, and Thrixopelma zaratensis Kaderka & Quispe-Colca, 2025 is newly transferred to Ewok gen. nov. with Ewok zaratensis syn. nov. placed as a juniorsynonym of Ewok christineae comb. nov.
