Diagnosis |
Diagnosis: lateral line complete, 23-29 (Ref. 81279) or 26-29 (Ref. 80290) lateral line scales. Anal fin with 3 unbranched and 15-19 (Ref. 81279) or 16-19 (Ref. 80290) branched rays. 11-14 gill rakers on lower part of first branchial arch; 6/8 premaxillary teeth (Ref. 2880, 81279). Inner dentary teeth conical, monocuspid; scales of flank without melanophores concentrated along basal margin, pigment diffuse or absent (Ref. 80290). Fins colorless, at most, pinkish; caudal fin tinged with pink (Ref. 2880, 81279). Tip of dorsal fin usually blackish (Ref. 2880, 80290, 81279). Widely distributed, never found in Cavally River (Ref. 2880, 81279).
Description: body slender; body depth 25-29% and head length 24-28% of SL (Ref. 80290). Body height 3.45-3.95x and head length 3.6-4x in SL (Ref. 42032). Mouth terminal, upper lip prominent, depth of lower jaw about 1.5 that of upper jaw; premaxilla with 3 teeth in outer row each bearing 5 cusps, 4 teeth in inner row each bearing 6-7 cusps; dentary with 4 teeth in outer row each bearing 5-7 cusps, median cusp prominent, a conical monocuspid tooth at symphysis posterior to outer row teeth; lateral line complete, 22-29 tubes, ultimate canal-bearing scale terminal (Ref. 80290). Very pronounced sexual dimorphism in male adults; anal fins curved instead of pointed (Ref. 2880, 81279).
Coloration: body silvery with glossy, brilliant longitudinal band; caudal fin tinged with carmin-pink; usually black spot at dorsal-fin tip (usually absent in very small specimens); lateral band black and appears to be broader posteriorly when preserved in formalin (Ref. 2880, 81279). |
