Africa: widely distributed in the Congo River basin (Ref. 28136, 47399), from the Lower Congo River near its estuary up to the Upper Lualaba River, but excluding the Luapula-Mweru (Ref. 188).

Maturity: Lm ? range ? - ? cm
Max length : 7.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 93833)
背棘 (总数): 0; 背的软条 (总数): 13-15; 臀棘 0; 臀鳍软条: 18 - 22; 脊椎骨: 42 - 45. Diagnosis: Body slender, its depth about 20-24% of standard length; scutes strongly keeled, beginning under pectoral fin base, with 10-15 pre-pelvic and 8-11 post-pelvic scutes; snout rather blunt or acute; lower jaw not or slightly projecting, included in upper when mouth closed, with small teeth limited to anterior part; pre-maxillae with a single row of 24-42 small conical teeth directed inwards; maxilla slender, its blade more than 3 times as long as deep, upper edge quite strongly ridged; posterior supra-maxilla slender, spatulate, with distinct anterior shaft, shaft longer than blade; lower gillrakers 17-24 (Ref. 188, 47399). Also characterized by 26-35 scales in a longitudinal series and anal fin with 18-22 rays (Ref. 47399). It differs from Microthrissa moeruensis in having a distinctly blunter snout and less scales in longitudinal series (Ref. 188, 47399).

Found in rivers and lakes, apparently in both still and running water; seems to occur in rather acid waters (Ref. 188).
