Description: Depth of body 3.3-3.5 times in total length; length of head 3.5-4.0 times in total length (Ref. 2988). Caudal peduncle 1.3-1.5 times as long as deep (Ref. 2988). Snout rounded, a little shorter than eye, which is 3.0-3.3 times in head length; interorbital width 2.5-2.6 times in head length; mouth terminal, 3.5 times in head length; lips thin; two barbels on each side, anterior a little shorter than eye, posterior a little longer (Ref. 2988). Dorsal fin with 3 spines and 7-8 soft rays, equally distant from centre or posterior border of eye and from base of caudal fin, border straight, last spine strong, bony, serrated and shorter than head length; anal fin with 3 spines and 5-6 soft rays; pectoral fin about 2/3 head length, not reaching pelvic fin; base of pelvic fin below anterior half of dorsal fin (Ref. 2988). Scales on lateral line 29-31, 2.5-3 scales between lateral line and pelvic fin, 12 scales around caudal peduncle (Ref. 2988).

Colouration: Silvery, brownish on the back; a dark dot at base of caudal fin (Ref. 2988).
