A new species of the genus Lipkemera Davie, 2010, is described from a submarine cave at Ie Island, Ryukyu Islands, Japan. Lipkemera iejima, new species, can be distinguished from congeners by the characters of ambulatory legs and the regionation of the dorsal surface of the carapace. The present study brings the number of Lipkemera species to five. A key to species of Lipkemera is also provided.
