Short description Claves de identificación | Morfología | Morfometría

Espinas anales: 0; Radios blandos anales: 21 - 22. Diagnosis: 4.5 scales between lateral line and dorsal fin origin; 18-19 anal fin branched rays; flanks with dark lateral pigment band from opercular margin to caudal fin; humeral spot present (Ref. 80290).

Affinities: most similar to Brachypetersius huloti from the Congo River basin, from which it differs in the extension of the lateral band onto the median caudal fin rays, presence of a humeral spot and fewer scales (4.5-5.5 vs 6.5) in transverse series between lateral line and dorsal fin origin (Ref. 80290).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01072 (0.00484 - 0.02371), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.1 ±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. 59153): Low vulnerability (10 of 100).
