Remarks Sexually mature males have no spines on simple rays; one row of large spines is present on 1st to 14th branched anal-fin rays, each ray with 6-13 hooks, located on most medial branch. From 12-18 large spines on branched rays of pelvic fin, located on both branches of rays, and extending on to anterior-most part.

Diagnosis

This species is distinguished from all its congeners, except Bryconamericus rubropictus and B. thomasi, by having five teeth on the maxilla (vs. 1 or 2 teeth on maxilla). It differs from these 2 species in having a reticulated pattern over the lateral stripe, generated by the concentration of melanophores, the scale margins, all along the sides of the body, by the number high of branched anal fin ray, vertebra, and the low number of branched dorsal fin ray. Dorsal prolongation of rhinosphenoid forming a bony wall between olfactory

nerves (vs. dorsal prolongation of rhinosphenoid between olfactory nerves absent); lateral process of palatine over the anterolateral margin of ectopterygoid (vs. palatine without lateral processes that laterally surpass the ectopterygoid); and distal tip of sphenotic spine, see laterally, wide and undulated (vs. narrow) (Ref. 93958).
