Two New Non-commensal Loxosomatids (Entoprocta: Loxosomatidae) from Okinawa and Sesoko Islands, Ryukyu Archipelago, Japan

抄録

Two new loxosomatids, Loxomitra ryukyuensis sp. nov. and Loxosomella parvipes sp. nov., are described from Okinawa Island and Sesoko Island, respectively, in the Ryukyu Archipelago, Japan. Both species were found on glass slides that had been immersed, respectively, in a fishery port or an aquarium at a marine station, which indicates that both are non-commensal species. Some individuals of L. ryukyuensis found in August were brooding embryos and larvae. Larval morphology is described for the first time in the genus Loxomitra.
