Two specimens (304.0–441.4 mm total length) of Uropterygius fasciolatus (Regan, 1909) were collected from Yonaguni-jima island, the westernmost island in Japan. This species was previously known from Indonesia, Papua New Guinea, the Solomon Islands, Palau, the Tokelau Islands, and the Phoenix Islands. Therefore, the present specimens represent the first record from Japan, as well as the northernmost record of the species up until now. A new standard Japanese name, “Murakumo-kikaiutsubo”, is proposed for the species.
