  Khantao gen. nov., a new genus of Selenocosmiinae Simon, 1889 from western Yunnan of China (Araneae: Mygalomorphae: Theraphosidae) Abstract The new genus Khantao gen. nov. from western Yunnan, China, is established for the subfamily Selenocosmiinae Simon, 1889, including three new species and one new combination: Khantao talpoides sp. nov. (type species); Khantao xuanae sp. nov.; Khantao ya sp. nov.; and Khantao xinhuaensis (Zhu & Zhang, 2008) comb. nov. (transferred from Selenocosmia Ausserer, 1871). DNA data (Cytochrome c oxidase subunit 1, COI sequences) are provided for all species. Yu, K., Wirth, V.V., West, R.C., Zhang, S. & Zhang, F.

Abstract
The genus Reversopelma Schmidt, 2001 is revised and diagnosed based on examination of the type material of its type species, R. petersi Schmidt, 2001, and a new species, Reversopelma spinometatarsi sp. nov., from Ecuador. The new species from Ecuador provides further knowledge on the male palpal bulb and spermathecal morphology of Reversopelma, supporting the delimitation of a new genus: Vitriemboli gen. nov. (type species Vitriemboli diaguita sp. nov.), easily distinguished from Reversopelma by the presence of urticating setae types III and IV. The Bolivian species Reversopelma herzogi Gabriel, Sherwood & Pérez-Miles, 2023 is transferred to Vitriemboli (Vitriemboli herzogi comb. nov.) based on urticating setae and male palpal bulb morphology. A second new genus, Colombiarachne gen. nov. (type species Colombiarachne dianae sp. nov.), discovered separately, is described from Colombia.
