Diagnosis

Diagnosis: flanks with intense pigment band from a vertical through anal fin origin and extending caudad to posterior margin of median caudal fin rays; 24-26 scales in longitudinal series; adipose fin broad and rounded, its total length 3x or more its length at base (Ref. 80290).

Description: body robust, greatest body depth 28-38% of SL and head length 26-29% of SL; mouth slightly superior, lower jaw prominent, its depth about 2x 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 4-6 cusps, a monocuspid inner dentary tooth present at symphysis posterior to outer row teeth; lateral line canal incomplete, 12-16 tubes, ultimate canal-bearing scale at vertical through middle of pelvic fin; adipose fin large, its posterior margin reaching beyond vertical through middle of caudal peduncle; anal fin with 3 unbranched and 18-22 branched rays (Ref. 80290).

Coloration: flanks silvery, scales of dorsum often with pigment concentrated at their base; conspicuous dark band restricted to caudal peduncle and mostly ventral to lateral line, its anterior limit at vertical through anal fin origin and extending caudad to posterior margin of median caudal fin rays; adipose fin red in life, violet-red in males; tip of pelvic fins black; fins otherwise yellowish to dusky; humeral spot often present (Ref. 80290).
