Abstract

During a field survey of Korean marine ciliates, we collected three ciliate species from the eastern coastal waters of the Yellow Sea. Based on the observation of living and protargol and wet silver nitrate stained cells, the ciliates, belonging to the classes Spirotrichea and Oligohymenophorea, were identified as Cardiostomatella vermiformis (Kahl, 1928) Corliss, 1960, Parallelostrombidium paraellipticum Song et al., 2018, and Pleuronema paucisaetosum Pan et al., 2015. Both Parallelostrombidium paraellipticum and Pleuronema paucisaetosum were described only from their type localities, i.e., brackish water, suggesting that they tolerate a broad range of salinity, while Cardiostomatella is marine ciliate and seems to be cosmopolitan. These three species were reported for the first time in Korea. Brief descriptions, remarks to justify their identity and to compare the present isolates with similar taxa, and photomicrographs were provided for the three species.
