Likely inhabits littoral to benthic zones over shell, sand and mud bottoms; no detailed information on diet exists, but species is likely to feed on small gastropods, as do other Synodontis species in Lake Tanganyika .
Dorsal spines (total): 2; Dorsal soft rays (total): 7; Anal spines: 3 - 4; Anal soft rays: 6 - 8; Vertebrae: 34. Body is compressed laterally, with a convex predorsal profile, interrupted by a ridge formed by dorsal rim of eye; head somewhat depressed . Eye dorsolateral, ovoid, its diameter 64.2-81.0 % of snout length . Mandibular teeth 17-26, short and unicuspid, arranged in a single transverse row . Maxillary barbel without basal membrane, lacking branches or crenelations, and extending at least to base of pectoral fin; lateral mandibular barbel extending to point just short of anterior margin of pectoral girdle, with 4-5 non-tuberculate branches, lacking secondary branches; medial mandibular barbel 1/2 to 2/3 length of lateral barbel, with 4-5 pairs non-tuberculate branches, lacking secondary branches . Dorsal fin spine long, striated, nearly straight, terminating in short, white filament; anterior margin of fin spine with 0-3 small serrations distally; posterior margin with small serrations distally . Pectoral fin spine roughly equal in length to dorsal fin spine, striated, slightly curved, terminating in short, white filament; anterior spine margin with many small, antrorse serrations; posterior margin with large, retrorse serrations along entire length . Adipose fin short, poorly developed, margin convex . Body with large spots, fin spines brown to black .: fusiform / normal.
