Africa: Mbonge River basin in Cameroon to the Shiloango River basin in Democratic Republic of the Congo (Ref. 81678 ). Also present 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 the rivers Konkouré (Ref. 3009 ) and Sassandra (Ref. 3057 ) are misidentifications of respectively Mastacembelus kakrimensis (Ref. 55095 ) and Mastacembelus praensis (Ref. 57415 ).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00295 (0.00138 - 0.00633), b=2.92 (2.73 - 3.11), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic Level (Ref. 69278 ):  3.9   ±0.6 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) . Price category (Ref. 80766 ):   Unknown .
