Etymology: Microthrissa: Grek, mikros = small + Greek, thrissa, -es = shad (Ref. 45335). More on author: Poll.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; pelagic. Tropical; 6°S - 10°S
Africa: endemic in Lake Mweru (Ref. 188, 28136) in Democratic Republic of the Congo (Ref. 47399) and Zambia (Ref. 52959).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 4.1 cm SL male/unsexed; (Ref. 246)
soft rays: 15 - 22;
Vertebrae: 39 - 41. Diagnosis: Body slender, depth about 20-25% of standard length; scutes strongly keeled, beginning just behind base of last pectoral fin ray, about 10-12 + 5-8; snout rather pointed; lower jaw slightly projecting, with small teeth; pre-maxillae with a single row of small teeth; maxilla slender, its blade a little more than 3 times longer than deep, upper edge a little ridged; second supra-maxilla slender, spatulate, with distinct anterior shaft; lower gillrakers 18-20 (Ref. 188, 47399). It resembles small Microthrissa congica, which has a much blunter snout and more anal finrays, 18-21 vs. 16-18 (Ref. 188).
A lacustrine species, but perhaps also in small streams or rivers feeding Lake Mweru (Ref. 188).
