Three species of Munida Leach, 1820 are reported from the shallow-water of the Ryukyu and Ogasawara Islands, southern Japan. The present record of Munida leptosyne Macpherson, 1994 greatly extends its geographical distribution northwards into the northern hemisphere, and the fresh color pattern of the species is described for the first time. Intraspecific morphological variations of Munida olivarae Macpherson, 1994, are discussed. The species usually inhabits in a small hole as probable empty tube of unidentified serpulid polychaete on the coral reef slopes. Munida kawamotoi sp. nov. is described on the basis of three specimens from Kume-jima Island of the central Ryukyus. This species appears closest to M. hyalina Macpherson, 1994, but is distinguished from the latter species primary by the structure of the seventh thoracic sternite, basal segment of the antennular peduncle, and fingers of the cheliped. The color photographs of three Munida species are also provided for their effective identification.
