Abstract

The rediscovery of the enigmatic subterranean characiform Stygichthys typhlops is reported almost a half-century after the collection of the holotype, the only specimen previously known. Thirty-four specimens were collected in two shallow hand-dug wells at the region of the type locality, c. 13 km south-west of the town of Jaíba, Minas Gerais, Brazil. These specimens provide new information on the morphology of this species, and for the first time on its life history. The conservation status of S. typhlops is discussed. The species is severely threatened by habitat loss caused by exploitation of the aquifer.

摘要

神秘的洞穴鲇形目Stygichthys typhlops 的重新发现,是在收集到模式标本近半个世纪后报告的,这是之前唯一已知的标本。在巴西米纳斯吉拉斯州杰伊巴镇西南约 13 公里的模式产地地区,从两个浅手挖井中采集到了 34 个标本。这些标本提供了有关该物种形态的新信息,也是首次提供其生活史的信息。讨论了 S. typhlops 的保护状况。由于含水层的开采,该物种的栖息地丧失严重,受到威胁。
