Anteholosticha bergeri and Bakuella granulifera were isolated from soil samples collected from Muuidong and Songdo-dong, Incheon and confirmed new to South Korea. Including these two newly recorded species, 11 species of Anteholosticha and four species of Bakuella have been recorded in South Korea to date. Anteholosticha bergeri was discriminated from congeners by following characters: cortical granules, 12-16 macronuclei, 5-8 midventral pairs, 2-3 pretransverse cirri, 4-6 transverse cirri, and three dorsal kineties. Bakuella granulifera was identified by cortical granules, 5-11 buccal cirri, 2-5 frontoterminal cirri, 2-5 midventral cirri rows, and 8-12 transverse cirri. The Korean A. bergeri population corresponds to the Austrian population, except for the number of marginal and transverse cirri, and the Korean B. granulifera population corresponds to the Namibian population, except for body size. In addition, small subunit ribosomal RNA(18S rRNA) gene sequences from both species were determined.

We collected ciliates from terrestrial and aquatic habitats in Korea. Morphology was examined based on observations of both living and stained specimens. As a result of the observations, we found 24 previously unrecorded ciliate species to Korea. The morphology of these species are briefly described here: Tracheloraphis dracontoides, Condylostoma arenarium, Aspidisca steini, Australocirrus aspoecki, Sterkiella tricirrata, Stylonychia lemnae, Wallackia bujoreani, Bakuella marina, Anteholosticha sigmoidea, Holosticha pullaster, Urostyla grandis grandis, Chaenea vorax, Enchelys gasterosteus, Phialina salinarum, Mesodinium pulex, Aegyria oliva, Bryometopus pseudochilodon, Pinacocoleps tesselatus, Urozona buetschlii, Colpidium colpoda, Campanella umbellaria, Pseudovorticella difficilis, Zoothamnium parahiketes and Z. plumula. Among these 24 ciliates, S. tricirrata and U. grandis grandis were studied based on both the morphology and the morphogenesis.
