Abstract

Two epistylid peritrichous ciliates collected from the littoral aquatic plants at pond in a suburb of Ulsan, Korea were identified as Epistylis plicatilis Ehrenberg, 1831 and E. hentscheli Kahl, 1935. The description was based on the observation of living specimens and protargol impregnated specimens. This study is about redescription compared with original description. These species have not been reported in Korea and their characteristics are as follows: E. plicatilis is thin, long funnel form and has compact stalk, while E. hentscheli is unsymmetrical bell form and has hollow stalk.

울산 인근의 연못 가장자리 수초에서 채집된 섬모충류가 겹가지섬모충과 (Epistylidae)에 속하는 겹가지섬모충(Epistylis plicatilis Ehrenberg, 1831)과 빈겹가지섬모충 (E. hentscheli Kahl, 1935)으로 각각 동정되어 재기재하였다. 이 종들은 한국에서 처음 보고되는 종들로서 생체표본과 protargol로 염색한 표본에 근거하여 재기재하였다. 원기재와 유사종들과 비교하였는데 겹가지섬모충 (E. plicatilis)은 가늘고 긴 깔대기 형태를 가지며 줄기는 근섬유로 속이 찬 형태이다. 반면에 빈겹가지섬모충 (E. hentscheli)는 비대칭의 종 모양을 띠며 줄기는 속이 텅 빈 형태이다.
