شوكة شرجية: 0; أشعه شرجية لينه: 21 - 22. Diagnosis: 4.5 scales between lateral line and dorsal fin origin; 18-19 anal fin branched rays; flanks with dark lateral pigment band from opercular margin to caudal fin; humeral spot present (Ref. 80290).
Body shape (shape guide): fusiform / normal.
Affinities: most similar to Brachypetersius huloti from the Congo River basin, from which it differs in the extension of the lateral band onto the median caudal fin rays, presence of a humeral spot and fewer scales (4.5-5.5 vs 6.5) in transverse series between lateral line and dorsal fin origin (Ref. 80290).
