青岛沿海的自由生聚缩虫属纤毛虫(原生动物,纤毛门,缘毛目)

INTRODUCTION TO FREE LIVING ZOOTHAMNIUM CILIATES FOUND IN QINGDAO,CHINA(PROTOZOA,CILIOPHORA,PERITRICHIDA)

涉及近年来采集自青岛沿海的自由生聚缩虫属纤毛虫14种,包括9个国内新纪录:交替聚缩虫Zoothamnium alternans Claparède & Lachmann,1859,弗氏聚缩虫Z.foissneri Ji et al.,2005,黑凯聚缩虫Z.hiketes Precht,1935,海洋聚缩虫Z.marinum Mereschkowski,1879,霉聚缩虫Z.mocedo Entz,1884,倪氏聚缩虫Z.nii Ji et al.,2005,拟树状聚缩虫Z.pararbuscula Ji et al.,2005,王氏聚缩虫Z.wangi Ji et al.,2005,许氏聚缩虫Z.xuianum Sunetal.,2005;以及其他5个已知种:群栖聚缩虫Z.commune Kahl,1933,双缘聚缩虫Z.duplicatum Kahl,1933,巨大聚缩虫Z.maximum Song,1986,羽状聚缩虫Z.plumula Kahl,1933,中国聚缩虫Z.sinense Song,1991。对以上各种作了简要的综合性描述,并给出了种检索表。

Zoothamnium is one of the most species-rich genera of peritrichs containing over 70 nominal species,most of which remain undescribed regarding the data of important criteria revealed with modern methods.Due to the lack of detailed information,especially that about the infraciliature and the silverline system,identification on Zoothamnium is still difficult.As a part of survey on marine ciliate fauna in the coastal waters of Qingdao（36°08 N,120°43 E）,studies on morphology of free-living peritrichs were carried out dring a period of 2002-2005 by the Laboratory of Protozoology,OUC. Based on riving morphology, infraciliature and silverline system, the morphological descriptions of 14 poorly-known species from.Qingdao coast are presented here,of which 8 are recorded for the first time in China;Zoothammium alternans Claparede＆Lachmann,1859,Z.commune KalI,1933,Z.duplicatum Kahl,1933,Z.foissneri Ji et al.,2005,Z.hiketes Precht,1935,Z.marinum Mereschkowski,1879,Z.maximum Song,1986,Z.mocedo Entz,1994,Z.nii Ji et al.,2005,Z.pararbuscula Ji et al.,2005,Z.plumula Kabl,1933,Z.sinense Song,1991,Z.wangi Ji et al.,2005,Z.xuianum Sun et al.,2005.A key for identification of above species is also provided.
