Etymology: Nannothrissa: Latin, nannus = small + Greek, thrissa, -es = shad (Ref. 45335). More on authors: Poll & Roberts.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; pelagic. Tropical; 0°S - 3°S
Africa: Lake Mai-Ndombe in the Democratic Republic of the Congo (Ref. 188, 28136, 94752).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 2.3 cm SL male/unsexed; (Ref. 188)
soft rays: 17 - 19;
Vertebrae: 38 - 39. Diagnosis: Body slender or moderate, depth about 25% of standard length; scutes a little behind isthmus, very strongly keeled, 9 + 7-9; lower jaw very slightly projecting, toothless; no teeth on premaxillae or maxillae; second supra-maxilla as deep as maxilla blade and with long slender anterior shaft; lower gillrakers 20-23; pelvic fin with 7 finrays, its insertion just below dorsal fin origin; anal finrays 17-19; scales in lateral series 34-35 (Ref. 188). It differs from Nannothrissa parva in having fewer gillrakers, 20-23 vs. 24-31, fewer anal finrays, 17-19 vs. 20-22, and fewer scales, 34-35 vs. 35-40 (Ref. 188).
A lacustrine species in acid waters (Ref. 188).
