Liobagrus chenghaiensis, a new species of catfish (Siluriformes: Amblycipitidae) from Yunnan, South China

Liobagrus chenghaiensis, new species, is described from Chenghai Lake, Yunnan Province, South China. It is distinguished from all other species of Liobagrus with a serrated posterior margin of the pectoral-fin spine by possessing a free apex on the posterior margin of the adipose fin. It is similar to L. marginatus in the presence of a subtruncate caudal fin, by which both are distinguished from all other Chinese congeners with a serrated posterior margin of the pectoral-fin spine. These two species are distinguished by differences in the body depth and the distance between the pelvic-fin insertion and the vent. Their distinction is also supported by osteological evidence.Liobagrus chenghaiensis, new species, is described from Chenghai Lake, Yunnan Province, South China.
