Herein, eyeless Pseudosinella species from Brazilian caves are reviewed, including the description of 23 new species, new records plus additional notes on the descriptions of P. ambigua Zeppelini, Brito, and Lima and of P. guanhaensis Zeppelini, Brito, and Lima. We also provide an identification key to 27 eyeless species recorded from Brazil. To organize the 26 Brazilian eyeless taxa analyzed in this work, we organize them in apparently artificial groups: 11 species have one larger tooth on the unguiculus outer lamella (petterseni group); one presents unguiculus outer lamella smooth or serrated (never with a larger tooth), with 9 held prelabral chaetae undivided and the last 6 held prelabral chaetae bifurcated. The Brazilian species of eyeless Pseudosinella herein described present a remarkably conservate dorsal chaetotaxy; therefore, the main diagnostic characters are related to other features like prelabral, labral, and ventral head chaetotaxy and empodial complex morphology. In addition, our study suggests that Brazilian caves possibly shelter a great diversity of Pseudosinella taxa, several of them potentially cave dependent.

巴西洞穴中无眼伪虫（跳虫科、昆虫科和鳞甲科）的回顾


本文回顾了巴西洞穴中的无眼拟西虫属物种，包括 23 个新物种的描述、新记录以及对P. ambigua Zeppelini、Brito 和 Lima 以及P. guanhaensis Zeppelini、Brito 和 Lima 描述的附加注释。我们还提供巴西记录的 27 种无眼物种的识别码。为了组织本次工作中分析的 26 个巴西无眼类群，我们将它们组织成显然是人工的类群：11 个物种的爪外层上有一颗较大的牙齿（ petterseni群）；一种的爪外层光滑或呈锯齿状（没有较大的牙齿），有9个保持唇前毛状体未分开，最后6个保持唇前毛状体分叉。本文描述的巴西无眼拟雉属物种呈现出非常保守的背侧毛毛排列；因此，主要的诊断特征与其他特征有关，如盂唇前、盂唇和腹侧头部的毛毛排列和心轴复杂形态。此外，我们的研究表明，巴西洞穴可能庇护着多种多样的拟黄藻类群，其中一些可能依赖于洞穴。
