It could be distinguished by a combination of the following characteristics: four pairs of barbels，short maxillary barbels，not reaching the pectoral-fin origin; adipose fin present，dissociated from the caudal peduncle; anal fin with 16–18 rays; anterior edge of pectoral and dorsal spines without serrations; a dark blotch appearing on the margin of the dorsal fin and stripes appearing on the upper and lower lobes of the caudal fin.
