Africa: Cuanza River in Angola (Ref. 52193, 128501), also Cunene, Okavango, upper Zambezi, Buzi and Pungwe rivers, and an isolated population occurs in the Ruo River (lower Zambezi system) in Malawi (Ref. 52193). In the Congo basin known from the Kwango in Angola (Ref. 11970). Possibly also in the Inkisi River (lower Congo) (Ref. 12818, 120641), Lufira and Luwombwa rivers (upper Congo basin) (Ref. 12818) but these need confirmation.
