Africa: rivers between Mbonge River basin in Cameroon and Shiloango River basin in the Democratic Republic of the Congo (Ref. 81678), and in the Congo River basin (Ref. 81678) from the Kinsuka rapids and Pool Malebo (Ref. 41585) up to the Wagenia Falls (Ref. 106245). Reports of Mastacembelus flavomarginatus from Kounkouré River (Ref. 3009) and Sassandra River (Ref. 3057) are misidentifications for respectively Mastacembelus kakrimensis (Ref. 55095) and Mastacembelus praensis (Ref. 57415).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00282 (0.00126 - 0.00629), b=2.96 (2.77 - 3.15), based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.3 ±0.4 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100) .
