Etymology: brevianalis: From the Latin "brevis" (short) and "anus" (here referring to the anal fin) because of the short anal fin and the low number of anal fin rays in the types of this species (Ref. 43912).

Known from the rivers Ogun (Ref. 13331), lower Niger (Ref. 13331, 57127), Kwa-Ibo and Cross in Nigeria (Ref. 43912, 57127), and the Wouri, Sanaga and Nyong in Cameroon (Ref. 7351, 43912, 81643). Report from Ogowe (Ref. 43912) refers to S. laticeps (Ref. 81643). Report from the Congo River basin (Ref. 51193) not confirmed in Ref. 43912, 78218 or 81643.

Diagnosis: small species, less than 100 mm long; eyes small, diameter not exceeding 23% of head length; inner margin of pectoral-fin spine weakly denticulate (Ref. 43912, 57127, 81643). Head rounded (Ref. 43912). Nasal barbels always extending beyond hind margin of eye (Ref. 57127, 81643) but not beyond anterior border of opercle (Ref. 43912). Adipose fin always present (Ref. 43912, 57127, 81643) and fully developed (Ref. 57127, 81643). 34-39 branched anal-fin rays and 6-8 gill rakers on lower limb of first gill arch (Ref. 57127, 81643). Colour pattern marbled (Ref. 43912, 57127, 81643). Barbels well developed (Ref. 81643). Posterior nostrils at same distance or closer to each other than the anterior pair (Ref. 43912, 81643).
