Abstract :A stygiobiont palaemonid prawn, Macrobrachium miyakoense Komai & Fujita, 2005, is recorded based on a female specimen collected from an anchialine cave in Ishigaki-jima Island, Yaeyama Island Group, Ryukyu Islands, southwestern Japan. This is the first distributional record of the species from outside Miyako-jima Island. The species is morphologically very similar to M. xmas, but the specimen was identified as M. miyakoense based on the eye stalk width, rostral shapes, and their distribution. Our observation indicates that these two species could not be identified based on one of diagnostic characters proposed in the original description (the number of teeth on the post-rostral margin of the carapace).
