Diagnosis

Diagnosis: Lateral line scales (43)45-49(51); above lateral line (9.5)10-11(10.5); right pharyngeal teeth 5-6 (Ref. 55426). Differs from its congeners by having eye diameter greater than snout length, usually 43-47 + 2-3 scales on lateral line and 3½-5 scale rows between lateral line and pelvic origin (Ref. 59043).

Description: Body relatively narrow, moderately laterally compressed body with rounded abdomen. Head relatively small, with length 20.54-25.28% in standard length; head depth about 1.6 times greater than caudal peduncle depth. Eyes are small and with inferior arched mouth, without a conspicuous horny blade on lower lip. Dorsal and anal fins similar in size, generally with 7 branched rays in dorsal and 7 or 8 in anal, both with slightly convex profile; origin of dorsal fin located above end of pelvic fins or slightly posterior to this; caudal fin with slightly rounded lobes. Scales numerous and of medium-size, with distinct and complete lateral line; small and numerous gill rakers, along entire gill arch; 6/5 or 6/6 smooth and knife-shaped pharyngeal teeth, in one row (Ref. 55426).
