Anabarilius macrolepis P. L. Yih & C. K. Wu

Yilong Whitefish (Anabarilius macrolepis)

This species was restricted to the Yilong Lake in Yunnan, China; in 1981, this lake dried out completely for about 20 days as a consequence of water extraction for agriculture.

The Yilong Whitefish had no chance to survive and is now extinct.

Yangzong Whitefish (Anabarilius yangzonensis)

The Yangzong Whitefish, which was described in 1980, was restricted to the Yangzong Lake in Yunnan, China.

The populations of the species collapsed due to pollution and the introduction of non-native fish species; it has not been found during the most recent surveys in 2008 and might well be extinct.
