Remarks. According to Miyamoto & Morino (2004) M. humicola and M. paludosus are very similar. They are separated by the pleopodal rami (about as long as the peduncle in M. paludosus and about half the peduncle length in M. humicola) and the uropod 3 ramus (about 0.7 × the length of the peduncle in M. paludosus and about half the length in P. humicola).

Distribution. Japan. Yokohama (Martens, 1868). Taiwan. Demao, Shuilien, Tachi and Fulung (Miyamoto & Morino 2004).
