Clés d'identification | Morphologie | Morphométrie
Rayons mous dorsaux (Total) : 11; Rayons mous anaux: 23 - 24; Vertèbres: 32. The following characters separate this species from all other Venezuelan congeners: dorsal fin with three unbranched and eight branched rays, except in Hyphessobrycon notidanos, Hyphessobrycon oritoensis, Hyphessobrycon fernandezi; maxilla short; maxilla with one pentacuspid tooth; dentary with eight teeth; premaxilla with 2-3 teeth in the outer row; lateral scales 28-29; predorsal scales 9; no sexual dimorphism; dark lateral band extending from the upper rear margin o the opercle to the caudal peduncle and continuing as a rhomboidal peduncular blotch onto the middle caudal fin rays (Ref. 79635).
