03FD87C72C53E5276CE1FEF4B947FB42.taxon	discussion	Remarks. Hemicycliostyla sphagni should be compared with two congeners, H. lacustris and H. marina. Hemicycliostyla sphagni differs from H. lacustris based on body length (230 - 340 μm vs. about 190 μm) and number of adoral zone membranelles (67 - 76 vs. 50 - 60) (Gellért and Tamás, 1958). Hemicycliostyla sphagni can be distinguished from H. marina based on its habitat (terrestrial vs. marine) (Kahl, 1932).

03FD87C72C53E5276CE1FB5FBD1EFE78.taxon	discussion	Remarks. The Korean population of Pseudokeronopsis songi corresponds to the Chinese population in body size, two types of cortical granules, five transverse cirri, and three dorsal kineties (Li et al., 2017). Pseudokeronopsis songi differs from P. pararubra in the number of transverse cirri (3 - 6 vs. 6 - 12) and dorsal kineties (3 or 4 vs. 4 - 8) (Li et al., 2017). Pseudokeronopsis songi differs from P. carnea in the number of dorsal kineties (3 or 4 vs. 5 - 8) (Li et al., 2017). Pseudokeronopsis songi differs from P. rubra in the number of transverse cirri (3 - 6 vs. 6 - 9) and dorsal kineties (3 or 4 vs. 5 - 8) (Wirnsberger et al., 1987).	en	Chae, Kyu-Seok, Kim, Kang-San, Jung, Jongwoo, Min, Gi-Sik (2023): Unrecorded species of Korean protozoans discovered through the project of ‘ Discovery of Korean Indigenous Species’ III.
