Neoplasioporus zocconis (Yamaguti, 1934) (Trematoda: Opecoelidae) was found from the intestine of the pale chub, Zacco platypus, for the first time in Korea. The worms were characterized morphologically by oval body shape, bipartited seminal vesicle, sinistrally located genital pore, and lobed ovary, and distinguished from the two other species of Neoplagioporous by body shape and distribution of vitelline follicles. The morphological characteristics, except the ovary, well corresponded to those of the previous descriptions. The morphological difference of the ovary was considered as a character of geographical phenotypic variation.
