The Three New Fish Species Beaufortia viridis, Beaufortia granulopinna and Microdous hanlini Found in China | CBCGDF Observation

Researchers from Shanghai Ocean University recently discovered three new fish species endemic to China: Beaufortia viridis, Beaufortia granulopinna and Microdous hanlini, Which were published in the international academic journals “Zoosystematics and Evolution” and “Zootaxa.”

According to the research paper published in “Zoosystematics and Evolution” , two new species, Beaufortia granulopinna and Beaufortia viridis, are described from the upper Pearl River system in southwest China. Both species share the characteristics of the Beaufortia pingi species group, including prominent vertical stripes on the lateral body and pinnate-type lower lips, distinguishing them from other Beaufortia species.

According to the research paper published in “Zootaxa”, Microdous hanlini, is the second new species in the genus Microdous discovered by the team after Microdous amblyrhynchos. It is found in south China's Guangxi Zhuang Autonomous Region and is named in honor of Professor Wu Hanlin, a renowned ichthyologist at Shanghai Ocean University.
