Africa: Okavango and Kafue system in southern Africa (Ref. 52193). Also in the lower (Ref. 42510, 41585), middle (Ref. 11970, 41590, 41591, 82705) and upper (Ref. 106245) Congo River basin. Reports from the upper Zambezi and some from the Kafue (Ref. 12524, 13337, 94654) are misidentifications of Nannocharax dageti (Ref. 95523).

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=0.00380 (0.00147 - 0.00981), b=3.11 (2.88 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

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