Two oxytrichid ciliates collected from the mosses and estuarine littoral in Korea were identified as Oxytricha longigranulosa Berger and Foissner, 1989 and O. marina Kahl, 1932. These species are reported for the first time from Korea. The description was based on living and protargol impregnated specimens. Diagnostic characters for each species are as follows. Oxytricha longigranulosa: Cell in vivo $80-115{ imes}30-50{mu}m$, mostly $90{ imes}40{mu}m$. Length/width ratio about 2.4/1. Cortical granules about $1{ imes}1.5{mu}m$ in size, colorless, arranged in short and discontinued longitudinal rows. Four frontoventral cirri. Adoral zone of membrane lies (AZM) covering 30-50% of cell length with 25-27 adoral membranelles (AM). Buccal area flat, typical Oxytricha pattern. Five transverse cirri, 19-23 right marginal cirri, 19-24 left marginal cirri, three caudal cirri, five dorsal kineties. Two macronuclear nodules 2 in number and spherical in shape, two micronuclei in number. Oxytricha marina: Cell in vivo $100-150{ imes}30-60{mu}m$. Cytoplasm colorless without cortical granules. Four frontoventral cirri. AZM covering 50% of cell length with 28-44 AMs, Buccal area flat, typical Oxytricha pattern. Five transverse cirri, 23-38 right marginal cirri, 19-25 left marginal cirri, three caudal cirri, five dorsal kineties. Two macronuclear nodules and spherical in shape, 1-5 micronuclei, mostly two in number.
