Two unrecorded ciliates from Korea, Nolandia nolandi (Kahl, 1930) Small and Lynn, 1985 and Nolandia sinica Chen et al., 2012, were collected from freshwater and brackish environments, respectively. Their morphology was examined based on the observation of living cells, protargol-impregnated, and scanning electron microscopy specimens. The phylogenetic analyses were performed using the 18S rRNA gene sequence obtained from a single cell of each species. The Korean population of N. nolandi is characterized by a size of 35-50 × 15-26 μm in vivo, elliptical body, 13 or 14 somatic ciliary rows with 10-12 transverse circles and single caudal cilium. Nolandia sinica is characterized by a size of 50-65 × 15-25 μm in vivo, elliptical body, 16-19 ciliary rows with 13 or 14 transverse circles and single caudal cilium. In the phylogenetic analyses, the genus Nolandia showed non-monophyly.
