Distinguished from known Bryconamericus species by: the insertion of the first three pterygiophores in front of the anal fin on the first caudal vertebra of the spine; a short ischium process; the dentition of eight small teeth; and the rhinosphenoid is wide in its posterior extreme where it makes contact with the cartilage (Ref. 49955).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 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).

Trofisk nivå (Ref. 69278): 2.6 ±0.3 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
