Africa: coastal fringes of the Volta basin. Seems to have replaced Pollimyrus isidori (continental) in the coastal basins or in the lower reaches of rivers in West Africa. Also known from the Mono River in Togo, Ouémé in Benin (Ref. 28663), Cross and Wouri (Ref. 81635). In the Congo basin, reported from the lower Congo basin (Ref. 1878), middle Congo River (Ref. 4910), Aruwimi and Lindi-Tshopo (Ref. 106290) in Democratic Republic of the Congo, and (middle) Congo River tributaries in Cameroon (Ref. 51193).
非洲: 僅限於佛塔河流域的海岸穗緣了。 似乎已經在海岸的流域取代 Pollimyrus isidori(大陸的) 或在非洲西方部取代河的範圍下游。 在多哥與貝南的 Oueme 河也已知來自剛果河流域，剛果與喀麥隆 (參考文獻 3203) 與 Mono 河。 (參考文獻 28663)
