摘要本文记述了新属Pauropygus gen。包括三个微小的种，盲目和无色素，生活在热带或亚热带国家的滨海间隙栖息地。其中有两个种为科学新种(模式种投射拟姬鼠Pauropygus Projectus sp.)N.来自新喀里多尼亚和太平洋Pauropygus sp.第三种原记述于隐翅虫属(Cryptopygus caussaneli Thibaud，1996)，具有较大的泛热带分布。我们在这里将1997年来自南非的Cryptopygus riebi Barra与Pauropygus caussaneli同义。墨西哥种Cryptopygus Axayacatl Palcios&Thibaud，2001的两个准型也变成了Pauropygus caussaneli，而该种的正型和剩余的准型支持它在原虫中的位置。在隐翅虫复合体中，Pauropygus gen.口器的特征(胸膜皱折上有两个大的突起，基侧野有6个毛状突起，改进的口器)和减少的感受器联结(圆锥形感受器2-3，0-1-2，1-2，1-2，1-3，微型感受器数量减少：00/0-100，感受器位于腹部的p排)。体型小、没有眼睛和色素也是其所有物种的共同特征。该属的三种不同的感受器毛序不同。
Abstract In this paper, we describe the new genus Pauropygus gen. n. which includes three minute species, blind and unpigmented, living in interstitial littoral habitats in tropical or subtropical countries. Two of these species are new to science (type species Pauropygus projectus sp. n. from New Caledonia and Pauropygus pacificus sp. n. from China); the third one, originally described in the genus Cryptopygus (Cryptopygus caussaneli Thibaud, 1996), has a larger pantropical distribution. We synonymize here Cryptopygus riebi Barra, 1997 from South Africa with Pauropygus caussaneli. Two paratypes of the Mexican species Cryptopygus axayacatl Palacios & Thibaud, 2001 turned also to be Pauropygus caussaneli, while the holotype and remaining paratypes of this species support its placement in Proisotomodes. Among the Cryptopygus complex, Pauropygus gen. n. is easily recognized by characters of mouthparts (presence of two large projections on pleural fold, basolateral field with 6 chaetae, modified mouthparts) and reduced sensillar chaetotaxy (tergal sensilla 2-3,0-1/0-1,0-1,1-2,1-2,1-3, microsensilla reduced in number: 00/0-100, with sensilla situated in p-row on the abdomen). Small size, absence of eyes and pigment are also shared by all its species. The three species belonging to the genus differ by sensillar chaetotaxy.
