Redescription of two soil ciliates, Anteholosticha bergeri and Bakuella granulifera, from South Korea

초록

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.
