背的软条 (总数) : 88; 臀鳍软条: 68. M. rajui differs from all other species of the genus by the following combination of characters: head short, snout blunt, skull length 3.4% TL, rostral fang with dorsal profile slightly convex forming an almost straight line with frontal profile of skull, dorsal fin origin above myomere number 7, anal fin origin below dorsal fin ray number 22, and no subdermal, lateral melanophores (Ref. 34506).
Body shape (shape guide): eel-like.
M. rajui 在组合特徵之后有别于所有的其他种的本属藉由: 头部短, 吻钝的,头盖骨长度 3.4% TL, 嘴的尖牙用背面轮廓些微中凸形成一几乎直线用头盖骨的前轮廓, 在 7 号 myomere 上面的背鳍起点, 在背鳍 22 号鳍条 , 与没有皮下又侧面的黑色素细胞之下的臀鳍起源.(参考文献 34506)
