An adult female of Lernanthropus chrysophrys Shishido, 1898 was collected from the gill filament of a blackhead seabream, Acanthopagrus schlegelii (Bleek- er, 1854), in coastal waters of Suruga Bay (western North Pacific Ocean), Shizuoka Prefecture, central Ja – pan. This represents the second record of L. chrysoph- rys from off the Pacific coast of Japan. Based on the previous and present papers, L. chrysophrys occurs in tropical to temperate waters of the Indo-West Pacific region and, in Japan, the species is found from waters affected by two warm currents, the Kuroshio and the Tsushima Current.
