Descripción breve
Claves de identificación | Morfología | Morfometría
Vértebra: 35. Distinguished from all other species of the genus by having upper jaw extending beyond lower, maxilla short with one or two teeth, cartilaginous rhinosphenoid extending to anterior part of prevomer, pelvic bone with cartilage along anterior edge, and lateral line pores in a straight line. Can be separated from the most similar Venezuelan species Bryconamericus subtilisform by possessing fewer pored lateral line scales 35-37 (vs. 38-39), more scales below lateral line to origin of pelvic fin 4-5 (vs. 2-3), more branched anal-fin rays 20-21 (vs. 17-18), and pelvic-fin rays usually ii,6 (vs. I,7).
Body shape (shape guide): elongated.
Found along shore over sandy substrates in mainstreams of rivers, as well as tributaries (Ref. 77139).
