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).
