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.
