Diagnosis |
Diagnosis: 10-12 gill rakers on lower limb of first arch; flanks with dark lateral pigment band continuous from opercle through caudal fin base and extending onto median caudal fin rays; dorsal and ventral caudal fin lobes with pigment stripe arranged more or less vertically across posterior third of fin (Ref. 80290). Description: body relatively robust, body depth 35-40% of SL and head length 25-28% 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, 32-35 tubes, ultimate canal-bearing scale contacting caudal fin rays by 1-2 non-canal-bearing scales; anal fin with 3 unbranched and 20-23 branched rays (Ref. 80290). Coloration: flanks silvery, with broad dark lateral pigment band more or less continuous from eye to caudal fin base, extending onto median caudal fin rays; dorsal and ventral caudal fin lobes with pigment stripe arranged more or less vertically across posterior third of fin; fins dusky, posterior third of dorsal fin and ventral margin of anal fin pigmented (Ref. 80290). |
