Maturity: Lm ? range ? - ? cm
Max length : 26.0 cm SL αρσενικό/απροσδιόριστο; (Ref. 34006); 20.4 cm SL (female)
Ραχιαίες άκανθες (συνολικά) : 0; Μαλακές ραχιαίες ακτίνες (συνολικά) : 0; Εδρικές άκανθες: 0; Μαλακές εδρικές ακτίνες: 9 - 11; Σπόνδυλοι: 37 - 43. Diagnosis: tooth patches broad; pectoral fin placed ventrally; 9-11 anal-fin rays; 19 caudal-fin rays (ii-7-8-ii; rarely i-7-8-ii, total 18); 3-4 gill-rakers on upper part of first arch; dorsum and flank marked by large blotches (up to 5-6 times an eye diameter); caudal saddle and bar pattern well-developed; 20-22 caudal vertebrae (Ref. 44050). 41-43 (Ref. 34006) or 37-39 (Ref. 44050) total vertebrae. Differs from M. minjiriya in having fewer vertebrae and a much narrower head and mouth, and smaller oral tooth bands; differs from M. cavalliensis in having more vertebrae and much smaller tooth bands (Ref. 34006).
