Short description
Morfología | Morfometría
Radios blandos dorsales (total): 11; Vértebra: 37 - 38. 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).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01585 (0.00663 - 0.03787), b=2.95 (2.77 - 3.13), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Nivel trófico (Ref.
69278): 2.6 ±0.3 se; based on size and trophs of closest relatives
Resiliencia (Ref.
120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
