Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt): 10; Wirbelzahl: 39 - 40. Diagnosed from other members of the genus in possessing nine proximal pterygiophores (including the terminal piece) on dorsal fin. Differs further from Hemibrycon species from the upper and middle Cauca rivers by having 43-46 pored lateral-line scales (Ref. 83513).

Inhabits creeks with brown water and substrate of stone and sand. The creeks are characterized by having 18.3-20.3°C surface temperature, 7.6-9.7 mg/l dissolved oxygen and 104-127% saturation, pH 8, and 2-4 m width (Ref. 83513).

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=0.00813 (0.00372 - 0.01775), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.4 se; based on size and trophs of closest relatives

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