Two fully matured specimens were collected from the blood vessel of two fish, Theragra chalcogramma, which was bought at the Emun market of Seoul in May, 1985. The blood fluke has no pharynx and suckers. Its body surface was covered with minute spines forming fan-shaped groups, 15 <m long. The intestine was H-shaped, and the ratio of esophageal length to body length was 1:6.1-6.8. Irregular shaped testes were 109-114 in number, occupying the intercecal space from cecal bifurcation to the genital pore. The present species was identified as Aporocotyle theragrae. This is the first report of the species in Korea.
