背棘 (總數) : 3; 背的軟條 (總數) : 8 - 9; 臀棘: 3; 臀鰭軟條: 5; 脊椎骨: 31 - 32. Body somewhat compressed (Ref. 53378). Predorsal profile convex with a noticeable nuchal hump (Ref. 53378). Eyes inclined noticeably upwards (Ref. 53378). Mouth relatively small, subterminal (Ref. 53378). Barbels are absent (Ref. 53378). Last simple dorsal ray smooth and flexible (Ref. 53378).

Scales radially striated (Ref. 53378): 22-25 lateral-line scales, 3½ scales between the lateral line and dorsal-fin origin, 3½ to 4½ scales between lateral line and mid-ventral line in front of the pelvic-fin origin, 2 scales between the lateral line and pelvic-fin origin, and 9 to 10 scales around caudal peduncle (Ref. 53378). The color in living specimens is generally pale silvery, the caudal fin tinged with pink (Ref. 53378).
