Abstract：
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.
摘要：
在这里，回顾了来自巴西洞穴的无眼伪细菌物种，包括23个新物种的描述，新的记录加上关于P.ambiguaZeppelini的描述的额外注释，布里托,还有利马和瓜巴塞·齐佩利尼，布里托,还有利马.我们还提供了来自巴西的27种无眼物种的识别钥匙。为了组织在这项工作中分析的26个巴西无眼类群，我们将它们组织在明显的人工组中：11种在unguiculus外层薄片上有一颗较大的牙齿（petterseni组）;一种表现出光滑或锯齿状的unguiculus外层薄片（从不带有较大的牙齿），其中9个保持前唇chaetae未分开，最后6个保持前唇chaetae分叉。本文描述的无眼假性鼻窦杆菌的巴西物种表现出明显保守的背侧毛囊；因此，主要的诊断特征与其他特征有关，如前唇，Labral,和腹侧头部角化和口状复杂形态。此外,我们的研究表明，巴西的洞穴可能栖息着各种各样的假人分类群，其中一些可能依赖洞穴。
