This fish can beeasily distinguished from all other congeners by externalmorphological characteristics, and is estimated to havediverged from its sister group about 0.55 million years ago(Ma). The geologically well separated locality of this specieshas expanded the distribution of Sinocyclocheilus cavefishfrom around N25°(latitude) to above N30°. Herein, wedescribe this new species as Sinocyclocheilus sanxiaensis sp.nov., and discuss the possible reasons why the speciesappears, surprisingly, in the Three Gorges reservoir.展开更多
