Size / Gewicht / Alter
Maturity: Lm ? range ? - ? cm
Max length : 37.2 cm SL Männchen/unbestimmt; (Ref. 44050)
Afterflossenstacheln: 0; Afterflossenweichstrahlen: 9 - 11; Wirbelzahl: 40 - 45. Medium-sized species probably attaining over 300 mm; vertebral counts 23+19+42(2); tooth bands moderately large, laterally and longitudinally moderately broad. Distinguished from the species in the Congo basin by its coloration, with relatively large blotches similar with M. electricus and M. minjiriya. Resembles M. electricus but differs in having more vertebrae (45 vs. 41-44), fewer gill rakers, and oral tooth bands that are laterally and longitudinally somewhat shorter. Holotype and paratype from the Shire have 2+21=23 and 3+18=21 gill rakers on the first gill arch (Ref. 34006). Tooth patches narrow; pectoral fin placed near the body mid-depth; 9 pectoral-fin rays; 9-11 anal-fin rays; total number of vertebrae 40-41; 7-8 branched caudal-fin rays; large blotches on dorsum and flank; base color grey; caudal fin at most lightly spotted (Ref. 44050).
