soft rays: 9 - 11;
Vertebrae: 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; 37-39 total vertebrae (Ref. 44050). Differs from M. minjiriya in having fewer vertebrae and a much narrower head and mouth, and smaller oral tooth bands.
