In this study, we present new records to Korea for three ciliate species[Apogonostomum pantanalense Foissner, 2016; Keronopsis polychaeta (Borror, 1966) Jankowski, 1979; Frontonia canadensis Roque and Puytorac, 1972] collected from marine (F. canadensis) and moss-covered soil(A. pantanalense and K. polychaeta) habitats. We examined the morphology of these three ciliates based on live observations and protargol impregnation. The main characters of the three ciliates are as follows: A. pantanalense: cell size approximately $130{\times}45{\mu}m$, tail-like posterior end, and 6 or 7 ventral cirral pairs elongated to transverse cirri; K. polychaeta: size approximately $140{\times}90{\mu}m$ and approximately 18 frontal coronal cirri and 5 transverse cirri; F. canadensis: cell size approximately $100{\times}50{\mu}m$ and approximately 88 somatic kineties, 3 or 4 vestibular kineties, and 5 postoral kineties.
