Abstract

Two oxytrichid ciliates collected from the two habitats (soil under pine forest near beach and sewage treatment plant) in Korea were identified as Oxytricha balladyna Song and Wilbert, 1989 and O. longa Gelei and Szabados, 1950. These species are reported in this paper for the first time from Korea. The description was based on the observation of living specimens and protargol impregnated specimens. Diagnostic characteristics for each species are as follows. O. balladyna: one micronucleus located between two macronuclei, five transverse cirri, three caudal cirri, five rows of dorsal kinety, no granule in cytoplasm. O. longa: each micronucleus closely located near two macronuclei, three postoral ventral cirri lying in a straight line and positioned far away from transverse cirri, four transverse cirri, two caudal cirri, four rows of dorsal kinety, yellow-green granules scattered on cytoplasm.

해안의 소나무 아래 토양과 하수처리장 폭기조에서 채집된 섬모충이 각각 Oxytricha balladyna와 O. longa으로 동정되었다. 이 종들은 한국에서 처음 보고 되는 것으로 생체표본과 protargol로 염색한 표본에 근거하여 재기재하였다. 유사 종들과 비교한 결과 Oxytricha balladyna는 한 개의 소핵이 두 개의 대핵사이에 위치하고. 5개의 후방극모, 3개의 미극모, 5열의 등쪽섬모열이 있으며 세포질에 granule이 없다. O. longa는 소핵이 각각 대핵 부근에 한 개씩 위치하며, 3개의 postoral ventral cirri가 직선상으로 배열하며 후방극모 (transverse cirri)와 멀다. 4개의 후방극모, 2개의 미극모와 4열의 등쪽섬모열이 있으며 특히 세포질에 Yellow-green granules이 관찰되어 특이하였다.
