| Remarks | Sexually mature males have seven to twelve spines on anterior branched anal-fin rays. Including longest anal-fin ray; one row of large hooks on 1st to 11th, each with 5-14 hooks. From 11-16 spines present along ventral surface of branched pelvic-fin rays; from 13-19 large hooks, located on both branches of rays, and extending on to anterior most part (Ref. 93958). |

| Diagnosis |
This species differs from all its congeners by having 7-8 scales between the lateral line and the pelvic-fin insertions (vs. 2-7, except Bryconamericus terrabensis with 7-8 and B. arilepis with 9-10); 33-38 branched anal-fin rays (vs. 31 or fewer); 28-31 anterior anal-fin rays covered by a row of scales at their bases (vs. 4-26); presence of a wide anterior maxillary tooth, at least twice as wide as the posterior tooth, both of which are pentacuspid (vs. maxillary teeth of same size) (Ref. 93958). Description: Anal-fin rays: iv-v, 33-38, v, 35 (Ref. 93958). |
