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).
