Two species of copepods, Lernanthropus atrox Heller, 1865, and Hatschekia pagrosomi Yamaguti, 1939, were collected from the gills of crimson seabream, Evynnis tumifrons (Temminck and Schlegel, 1843), in Hiroshima Bay, the Seto Inland Sea, western Japan. This collection represents a new host record for L. atrox and the first record of H. pagrosomi from E. tumifrons in Japan. The hosts and geographical distribution of these copepods are also reviewed.
