Etymology: Tylochromis: Greek, tylos = callus + Greek, chromis = a fish, perhaps a perch (Ref. 45335);  sudanensis: Named by Daget (1954) presumably in reference to the middle Niger localities he sampled in the French Sudan; the French term "soudanienne" (Soudan) is anglicized by Beadle (1974) and Lowe-McConnell (1975, 1985) as "soudanian" (Ref. 52346).
