简单描述
型态特徵 | 形态测量图
A relatively small species (largest known
specimen 56.7 mm SL) of the genus Bryconamericus Eigenmann, 1907 (type-species: B. exodon Eigenmann, 1907). The new species is characterized by the following features: (1) body depth relatively low (3.49 – 4.16), (2) anal-fin with 19 – 21 branched rays, (3) 17 – 21 setiform gill-rakers, (4) 38 – 41 scales in a longitudinal row, (5) 4½ – 5/1/3 transversal scales, (6) 37 – 40 vertebrae (total), (7) two to three tri- to quincuspid maxillary teeth, and (8) premaxilla in the outer row with four to five (mostly five) tri- to quincuspid teeth which are implanted in a irregularly row (Ref. 84136).
