| Remarks | Males differ from females by possessing the following characters: a row of short hooks on the last simple anal-fin ray and on the first to eleventh branched anal-fin rays, each ray with 7-15 hooks, located on the posterior-most branch; and 7-12 small hooks on the simple and branched rays of the pelvic fin, located on both branches of the rays, but not extending onto the anterior-most part (Ref. 86277). |

| Diagnosis |
Distinguished from congeners by having the following characters: incomplete lateral line, except Bryconamericus delta; anal fin with four or fewer unbranched rays; a short and thickened extrascapular bone which lacks or has only a reduced apophysis on its posterior tip, and only a few perforations by the latero-sensory canal; and live coloration. Differs from those that occur in the same basin: from Bryconamericus alpha by having 5 or 6 lateral teeth on the dentary (vs. 4), from Bryconamericus cristiani by the arrangement of the teeth in the outer premaxillary row in straight line (vs. zigzag), from Bryconamericus cismontanus and Bryconamericus loisae by its anal fin with 19-25 branched rays (vs. 13-18 and 26-30, respectively) (Ref. 86277). Description: Dorsal-fin rays iii,7-8; anal-fin rays iii-iv,19-25; pectoral-fin rays ii,10-11; pelvic-fin rays ii,6; scale rows between lateral line and pelvic-fin origin 4-5, usually 4 (Ref. 86277). |
