Africa: endemic to the Niger River basin, including the Benue (Ref. 57223). Report from the Ouémé (Benin) (Ref. 3202) refers to misidentified S. melanopterus specimens (see DVD version of Ref. 57223). Report from the Chari-Logone (Chad basin) in Central African Republic (see map in Ref. 57223) questionable.
