Schilbe yangambianus closely resembles S. brevianalis from Cameroon and Nigeria but in the latter species the nasal barbels are generally considerably shorter (not reaching beyond the anterior border of the opercle); S. yangambianus also resembles the sympatric S. marmoratus, especially by the similar coloration pattern, but both species are easily distinguished by the absence of an adipose fin in S. marmoratus (Ref. 43912).Coloration: preserved and live specimens: rather large variation in colour pattern; many specimens with head, back, sides and belly irregularly brown marbled; belly and underside of head often speckled with brown; striking dark brown or blackish blotch present above pectoral spine, where swim-bladder lies close below skin; all fins irregularly greyish or brownish, pectoral fins darker than others; pelvic and anal fins often with more or less dark band along base and border, variable in position; caudal fin darker at base (Ref. 43912). Based on Matthes (1964): entirely brownish-purple with black marblings and a distinct, postopercular, round spot, the area between this spot and the ventral fins darker; eye dark brown; fins brown-reddish, with dark brown marbling, pectoral fins dark, pelvic, anal and caudal fins yellowish at base (Ref. 43912).
