A new species of stygobitic palaemonid prawn of the genus Macrobrachium Spence Bate, 1864, is described from Christmas Island, Indian Ocean Territory, Australia. The new anchialine species resembles M. miyakoense Komai & Fujita, 2005, from Japan, but can be distinguished by its relatively longer and more slender rostrum, the proportionately smaller eye cornea with a more swollen eye stalk, and more teeth on the post-rostral margin of the carapace. The taxonomy of M. miyakoense is also discussed based on additional material recently obtained from Japan, and the species rediagnosed. Macrobrachium miyakoense was originally described from two young males collected from Miyako Island, Ryukyu Islands, Japan.
