Abstract / Introduction / Summary:
Adult females of the cymothoid isopod Anilocra clupei Williams and Bunkley-Williams, 1986 were collected from the body surface of Japanese sardinella Sardinella zunasi (Bleeker, 1854) (Clupeiformes: Dorosomatidae) from both a river mouth area of the Saba River flowing into the western Seto Inland Sea, and Kadogawa Bay, an inlet of the western North Pacific Ocean, in western Japan. These waters lie in Yamaguchi Prefecture (western Honshu Island) and Miyazaki Prefecture (eastern Kyushu Island), respectively. In Japan, A. clupei has so far been recorded from eight prefectures (Miyagi, Tokyo, Shizuoka, Shimane, Hiroshima, Ehime, Fukuoka, and Okinawa), and this species is herein reported for the first time from Yamaguchi and Miyazaki prefectures.
