During our investigation of ciliates from Korea, four ciliates were isolated from the non-flood Petri dish culture of soil. They were cultured under laboratory condition and studied using standard methods morphologically, including living observations, protargol impregnations, and morphometrics. The four species are Metopus hasei Sondheim, 1929, Urosomoida agiliformis Foissner, 1982, Oxytricha proximata Shibuya, 1930, and Cladotricha sp. in Nießen (1984) respectively.
