Africa: coastal basins from the river St. John in Liberia to lower Cameroon and the Benito River in Equatorial Guinea, in forest and northern adjoining savannah; also known from the Niger and the Bénoué River (Ref. 53405). Previously, two subspecies were recognized: Chromidotilapia guntheri guntheri and Chromidotilapia guntheri loennbergi.
