Diagnosis |
Can be diagnosed from other members of the genus Hyphessobrycon by the possession of a well-defined, oblique and marginal black stripe on each lobe of the caudal fin. Differs further from its congeners by the combination of the following characters: maxilla with 1-3 teeth, bearing 3-10 cusps; outer premaxillary row with 2-3 small teeth, bearing 5 or 7 cusps; iv-v, 27-36 anal-fin rays; 33-36 scales on the longitudinal series; two vertically elongated dark humeral spots; black caudal spot rounded or fan-shaped; dorsal and anal fins with the first rays dappled in black; and presence of minute bony hooks on the dorsal, anal and caudal fins of the mature males (Ref. 83966). Description: Dorsal fin ii,8-iii,9; anal fin iv,27, v,27, vi,27, iv,28, v,28, iv,29, v,29, iv,30, v,30, iv,31, iv,35, or iv,36; pectoral fin i,10, i,11, or i,12; pelvic fin i,6 (Ref. 83966). |
