Liobagrus is a genus of catfishes of the family Amblycipitidae. Liobagrus fishes are distributed in the Yangtze River basin, Taiwan, Japan, and the Korea Peninsula. The adipose fin of these fishes is a confluent with the caudal fin. The nostrils are far apart, unlike those found in Amblyceps. Most Liobagrus species grow to about SL.
Taxonomy
No shared derived characteristic has been found to diagnose the genus Liobagrus. However, it is maintained that this genus is currently monophyletic. Liobagrus has been placed in the family Bagridae. Later, it was found to more closely resemble Amblyceps, and was transferred to Amblycipitidae.
Xiurenbagrus was erected because Liobagrus would not be monophyletic with Liobagrus xiurenensis, now Xiurenbagrus xiurenensis. The genera Amblyceps and Liobagrus are sister group pair that is, in turn, sister to Xiurenbagrus.
