This genus is further characterized by the wide mouth (gape same of the head width), short barbels (occasionally reaching pectoral-fin origin), small eyes without free orbital margin, absence of axillary pore, a dark saddle straddling supraoccipital area to the end of dorsal-fin base, pre-maxillary dental plate with rounded margin and thin mesocoracoid arch (Shibatta, 2003a; 2003b).
