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.
