| Notas | Males with bony hooks in all fins; ray bifurcations of dorsal, pelvic and caudal fins with few bony hooks. These hooks are especially numerous at the pectoral and anal fins, with 2-3 bony hooks in each ray segment. Morphology of anal fin similar for both sexes, but somewhat more concave in females. In addition, females have greater standard length and body depth than males. |

| Diagnose |
This species can be distinguished from all its congeners, except Hyphessobrycon langeanii Lima & Moreira, in having a well-defined, round to horizontally oval humeral spot. It differs from H. langeanii by the possession of a second humeral spot (vs. absent), maxilla not reaching anterior edge of orbit (vs. maxilla reaching middle of orbit) and infraorbitals 3 and 4 separated (vs. coossified). Other diagnostic characters of H. togoi include: a short expanded maxilla with 1 large multicuspid tooth; premaxilla with an outer row of 3 small teeth, with 5 or 6 cusps, relatively apart from each other; an inner series with 5 teeth that are distally broader, with numerous cusps (6-11) and overlapping each other; iv-v, 17-20 anal-fin rays; 31-36 scales on the longitudinal series; presence of bony hooks on all fins of the mature males (Ref. 57841). Description: Pectoral-fin rays i, 9-11. Pelvic-fin rays i, 6-7, pelvic fin with axillary scale. Anal-fin rays iv-v, 17-20. |
