Abstract

A new species of swimming crab belonging to the genus Catoptrus A. Milne-Edwards, 1870, is described based on a single female specimen collected from a submarine cave at Ie Island, Ryukyu Islands, Japan. The new species can be easily distinguished from all five congeners by its proportionally longer pereopods as well as by combinations of the characters of the carapace, eyes, and cheliped.
