Abstract :This paper reports the first records of Hyastenus ambonensis Griffin & Tranter, 1986 from the Ryukyu Archipelago and H. uncifer Calman, 1909 from Okinawa Island. Hyastenus brockii De Man, 1888 is excluded from the carcinological fauna of Japan, because the only Japanese specimen from Kuro Island, Yaeyama Group, deposited at the Wakayama Prefectural Museumm of Natural History, is found to represent H. ambonensis. Diagnostic characters of closely allied H. ambonensis and H. baru Windsor & Ahyong, 2013 are reassessed.
