Abstract
An independently derived, blind, cave-dwelling amphipod, Minamitalitrus zoltani gen. nov., sp. nov. is described from the Hoshino-do cave on the island on Minami–Daitō jima, Okinawa, Japan. This genus belongs to the Talitrus group of 15 genera and is the first record of the group from Japan. Several characters support the new genus, particularly the re-duced biramous pleopods.
