背棘 (总数) : 0; 背的软条 (总数) : 0; 臀棘: 0; 臀鳍软条: 9 - 11; 脊椎骨: 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).
有别于 M. minjiriya 有比较少的脊椎骨与一个非常狭窄的头部与嘴 , 与比较小的口部齿箍。 有别于 M. cavalliensis 有更多的脊椎骨与较小齿箍。
