Abstract:
A blind fish of Sinocyclocheilus (Cypriniformes: Cyprinidae) was caught in open water in the Three Gorges (Sanxia) reservoir, at a depth of 20 m in the mainstream of Yangtze River in Zigui County, Hubei Province, China. This fish can be easily distinguished from all other congeners by external morphological characteristics, and is estimated to have diverged from its sister group about 0.55 million years ago (Ma). The geologically well separated locality of this species has expanded the distribution of Sinocyclocheilus cavefish from around N25° (latitude) to above N30° . Herein, we describe this new species as Sinocyclocheilus sanxiaensis sp. nov., and discuss the possible reasons why the species appears, surprisingly, in the Three Gorges reservoir.
