We verified three ciliates - Dysteria brasiliensis Faria et al., 1922, Dysteria lanceolata Claparède and Lachmann, 1859, and Dysteria ovalis (Gourret and Roeser, 1886) Kahl, 1931 - as previously unrecorded species in Korea. These three ciliates were collected from Incheon Harbor and Geojin Harbor in Korea. We describe the three species based on live observations, protargolimpregnated specimens, and silver nitrate-impregnated specimens.
