Abstract
1. Metacercariae were found from 6 samples among 4,382 Parlemon nipponensis which were caught at Podu, Kohung, Korea. 2. The metacercaria was inclined as a larval stage of Paragonimus westermani by following reason; i) Semisulcospira libertina was the only one species which lives in Podu area. ii) No other metacercaria except Paragonimus westermani were found from the craw or cray fish which were caught in the endemic aera. iii) Metacercariae, ovary, testes and cuticular spines resmbled the characteristics of Paragonimus westermani, which have been described by previous workers.
