Types. Lectotype, ZMB 2809 a, paralectotypes, ZMB 2809 b.

Additional material. Two specimens, ZMB 3457 as additional material 809.

Type locality. Yokohama , Japan .

Ecological type. Marsh-hoppers.

Habitat. Living under fallen leaves and grass in the coastal area in the northern region (Demao, Shuilien, Tachi) and a garden near the coast of Fulung in Taiwan.

Size. Male, 7–8 mm, female, 8–10 mm.

Diagnosis (male). Based on Miyamoto & Morino (2004).

Pleopods rami about half the peduncle length. Uropod 3 ramus about half the length of peduncle. Telson completely cleft, with 4 robust setae per lobe.

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).
