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. China ( Beijing , Hebei , Henan , Jilin , Liaoning , Shaanxi , Tianjin , Tibet ).
