Munida michaeli, a new species of deep-sea squat lobster (Munididae), is described and illustrated on the basis of a single male specimen collected off Okinawa Island, Ryukyu Islands, Japan, at depths of 641-650 m. It closely resembles M. sacksi Macpherson, 1993 known with certainty only from the Philippines, but different spination of the carapace dorsum and the greatly reduced armature of the flexor margins of the ambulatory dactyli distinguish the new species from the latter. With the addition of the present new species, 41 species of Munida Leach, 1820 are now known from Japanese waters.
