  Joining the dark side: waterfall spiders in subterranean habitats, with the description of a new genus and two new species from Brazil (Araneae: Trechaleidae) Abstract Trechaleidae is a family of spiders often recognized by its semiaquatic species, but its diversity extends beyond these well-known examples. In this study, we describe Troglotrechalea gen. nov. , a new genus with two novel species, T. faleroae spec. nov. and T. agorai spec. nov. , found exclusively in subterranean habitats within karst formations in central and southeastern Brazil. Both species exhibit pale coloration, but unmodified eyes and legs if compared to other species in the family. The slight degree of troglomorphism, along with their geographic and habitat records, suggests that these species are restricted to hypogean habitats, although they probably move through epigean habitats. Additionally, we report in detail the occurrence of the trechaleid genera Enna O. Pickard-Cambridge, 1897, Heidrunea Brescovi...

Systematics of the Western Ghats endemic tarantula subfamily Thrigmopoeinae with the description of a new genus and four new species

Abstract
The Western Ghats are a biodiversity hotspot known for its high degree of endemism. The tarantula subfamily Thrigmopoeinae, with two genera and seven species, is endemic to the Western Ghats. A taxonomic account of the Western Ghats endemic tarantula subfamily Thrigmopoeinae is presented. The study is based on a re-examination of existing museum material and a fresh collection from across the Western Ghats. Rediagnosis of the genera Haploclastus Simon, 1892 and Thrigmopoeus Pocock, 1899, is presented with a description of a new genus and four new species. The genus Cilantica gen. nov. is proposed to accommodate Cilantica phsycadelicus comb. nov. and Cilantica kayi comb. nov., and a new species from the southern Western Ghats. Thrigmopoeinae, being endemic to the Western Ghats, a biodiversity hotspot, is a vital flagship for invertebrate conservation.
