This species is distinguished by the following characters: pelvic fin rays 11-12 (usually 12); pectoral fin rays 13-15 (seldom 16); short projecting snout, 15-18% HL; short barbel, 3-4% HL, large orbit diameter, 35-40% HL; infraorbital width 8-10% HL; moderately long preopercular supporter, with obtuse angle at rear margin, 5-7% HL; 21-24 gill rakers; ventral striae reaching to ½ distance from pelvic fin bases to periproct; otolith has high predorsal lobe, with colliculi separated, closely placed across collum, with occasional tendency to partly join, terminating at some distance from anterior and posterior rims of otolith; otolith length to height (OL:OH), 0.95-1.1; total colliculum length to pseudocolliculum length (TCL:PCL), 1.6-1.7 (Ref. 98298).
Cross section: compressed.
