Issue
Paugy & Schaefer (2007: Ref. 80290) put the validity of the species in doubt as being a morphotype of Brycinus macrolepidotus Valenciennes 1850. This requires confirmation most likely through genetics studies (Paugy, pers,comm., 21 Mar. 2013).

Bayesian length-weight: a=0.00589 (0.00243 - 0.01426), b=3.13 (2.92 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

устойчивость к внешним воздействиям (Ref.
