; Água doce pelágico(a,os,as); pH range: 6.5 - 7.5; dH range: 10 - 25. Tropical; 23°C - 27°C (Ref. 2060)
Africa: widely distributed in the Congo basin; elsewhere, known from Lower Guinea (Cross, Ntem, and Ogowe rivers), the Niger, and Zambezi rivers and lakes Chad, Mweru, and Tanganyika (Ref. 122734); and in the Lukuga River only known downstream of Niemba (Ref. 36901, 42032). Reports from Lake Tanganyika (Ref. 80290) and Cubango/Okavango in Angola (Ref. 5331) needs confirmation (Ref. 120641).
Tamanho / Peso / Idade
Maturidade: Lm ? range ? - ? cm
Max length : 10.6 cm TL macho/indeterminado; (Ref. 2880)
Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 10; Espinhos anais: 0; Raios anais moles: 17 - 22. Diagnosis: lateral line always complete, 24-27 (Ref. 80290) or 27-30 (Ref. 81279) lateral line scales. Anal fin with 3 unbranched and 15-18 (Ref. 80290) or 14-19 (Ref. 81279) branched rays. 10-15 (Ref. 80290) or 10-14 (Ref. 81279) gill rakers on lower part of first branchial arch. 6/8 premaxillary teeth; fins colorless or, at most, pinkish; tip of dorsal fin hyaline (Ref. 2880, 81279), no black apical tip (Ref. 80290). Scales of flank with melanophores concentrated on basal margin (Ref. 80290).
Body shape (shape guide): fusiform / normal.
Affinities: M. humilis is most similar and possibly conspecific with M. stormsi Boulenger, 1902, and M. sardina Poll, 1938; apart from coloration, it is distinguished from latter two species on the basis of slight differences in overlapping features (see Ref. 80290).
