Africa: Congo River basin in Democratic Republic of the Congo (Ref. 188, 28136), including Lake Tumba (Ref. 41580, 93833), Ruki River (Ref. 93833) and Ubangui River (Ref. 45441). Reported also from near Kinganga in Lower Congo River (Ref. 42510), but its presence is not confirmed (Ref. 94750).

Duri punggung (Keseluruhan (total)) : 0; duri punggung lunak (Keseluruhan (total)) : 12 - 15; Duri dubur: 0; Sirip dubur lunak: 20 - 23; vertebrata, bertulang belakang: 39 - 40. Diagnosis: Body slender, depth about 20% of standard length; scutes beginning at isthmus, or just behind, very strongly keeled, 12-15 pre-pelvic and 6-8 post-pelvic scutes; lower jaw projecting, toothless; no teeth on premaxillae or maxillae; posterior supra-maxilla as deep as maxilla blade and with long slender anterior shaft; lower gill rakers 24-31; pelvic fin with 1 unbranched and 6-7 branched rays, its insertion just before dorsal fin origin; anal fin rays 20-23; scales in lateral series 35-40 (Ref. 188, 2263). It differs from Nannothrissa stewarti in having more gillrakers, 24-31 vs. 20-23, more anal fin rays, 20-23 vs. 17-19, and more scales in lateral series, 35-40 vs. 34-35 (Ref. 188, 2263, 94752).
Body shape (shape guide): fusiform / normal; Cross section: compressed.

Biologi     Daftar kata (contoh epibenthic)

Found in rivers and lakes, apparently in both running and still water, often in huge schools (Ref. 188). Feeds on plankton, including unicellular algae, diatoms and especially copepods, but also hydracarians and aquatic insects (Ref. 188, 41580). It breeds in Lake Tumba, ripe fishes being caught in late August and ripe and some spent fishes occurring in about mid-September (Ref. 188, 41580).
