Diagnosis: 4.5 scales between lateral line and dorsal fin origin; 18-19 anal fin branched rays; flanks with dark lateral pigment band from opercular margin to caudal fin; humeral spot present (Ref. 80290).

Description: body moderately robust, greatest body depth 35-38% of SL and head length 30-33% of SL; mouth terminal to slightly superior, lower jaw prominent, its depth about 1.5x that of upper jaw; premaxilla with 2 teeth in outer row each bearing 3-5 cusps, 4 teeth in inner row each bearing 5-7 cusps; dentary with 4 teeth in outer row each bearing 5-7 cusps, a monocuspid inner dentary tooth present posterior to outer row teeth; lateral line canal complete, 25-27 tubes, ultimate canal-bearing scale separated from caudal fin rays by 2-3 non-canal-bearing scales; anal fin with 3 unbranched and 18-19 branched rays (Ref. 80290).

Coloration: flanks yellow-silver; broad distinct dark lateral band more or less continuous from opercular margin to posterior margin of median caudal fin rays; ovoid humeral spot often present in larger individuals; dorsum with diffuse pigmentation, somewhat darker than ventral half of body, tending toward multiple faint lateral bands in larger individuals; fins generally dusky to yellowish in life (Ref. 80290).
