Remarks.

Most male specimens displayed a rounded lobe on the pereopod 7 carpus tergal margin, except for three specimens from Beijing and Henan province. M. sinensis is close to M. satsumaensis (Nunomura, 1987) in terms of noduli laterales’ positions and the morphology of pleopod 1 exopod, but it could differ in the antennal flagellum distal article as long as proximal article rather than 1.5 × as long as proximal article.

Distribution.
