Africa: middle Congo River basin (Ref. 188, 28136) and its tributaries north of the equator (Ref. 3509, 47399, 122734), apparently not in Kasai River and its tributaries (Ref. 188). Its presence in Lualaba River is questionable and possibly based on a labelling error (Ref. 47399).
Tamanho / Peso / Idade
Maturity: Lm ? range ? - ? cm
Max length : 9.9 cm TL macho/indeterminado; (Ref. 3509)
Espinhos dorsais (total): 0; Raios dorsais (total): 11-14; Espinhos anais 0; Raios anais : 22 - 27; Vértebras: 37 - 41. Diagnosis: Body rather deep, its depth about 30-37% of standard length; scutes strongly keeled, 1 or 3 before base of first pectoral fin ray, 13-16 pre-pelvic and 3-7 post-pelvic scutes; snout fairly pointed; lower jaw not or slightly projecting, included in upper when mouth closed, with small teeth limited to anterior part; pre-maxilla with medial notch and 16-26 small conical teeth directed outwards; maxilla blade slender, more than 3 times as long as deep, upper edge with a ridge flared outward; posterior supra-maxilla small, spatulate, shaft as long as or longer than blade; lower gillrakers 14-17 (Ref. 188, 47399). Also characterized by 34-41 scales in a longitudinal series and anal fin with 22-27 rays (Ref. 188, 47399). It resembles Microthrissa minuta, which has more lower gillrakers but fewer anal fin rays, 18-22 and 18-21 respectively (Ref. 188, 47399). It is distinguished from Microthrissa whiteheadi by the presence of a medial notch in pre-maxilla and a lower number of teeth on the pre-maxilla, 16-26 vs. 32-40 (Ref. 46514).
A riverine species (Ref. 188).
