Abstract / Introduction / Summary:

An adult female of Argulus coregoni Thorell, 1864 was collected from the body surface of a white-spotted char, Salvelinus leucomaenis (Pallas, 1814), in the up- per reaches of the Maze River, a tributary of the Hida River draining into the Nagara River, Gifu Prefecture, central Japan. This represents the first record of A. coregoni from a wild salmonid population in the pre- fecture, and the species is briefly described based on the female collected.
