广东沿海的砂壳纤毛虫及3种国内新纪录

TINTINNID CILIATES FROM COASTAL WATERS OFF GUANGDONG,WITH NOTES ON THREE NEW RECORDS OF CHINA (PROTOZOA,CILIOPHORA)

对广东沿海的砂壳纤毛虫进行了初步研究,涉及7属16种,其中3种确定为中国的新纪录:僧帽壳铃虫Codonella apicata Kofoid&Campbell,1929,陀螺形拟铃虫Tintinnopsis turbo Meunier,1919和膨胀细壳虫Stenosemella expansa Wailes,1925。另有3种为我国亚热带海域的新纪录:筒状拟铃虫Tintinnopsis tubu-losoides Meunier,1910,罗氏拟铃虫Tintinnopsis lohmanni(J rgensen,1927)Laackmann,1906和贪婪铃壳虫Codonella rapa Kofoid&Campbell,1929。其余10种为常见种:百系拟铃虫Tintinnopsis beroidea Stein,1867,尖底拟铃虫Tintinnopsis acuminata(Daday,1887)Kofoid et Campbell,1929,妥肯丁拟玲虫Tintinnopsis to-cantinensis Kofoid&Campbell,1929,筒状拟铃虫Tintinnopsis tubulosoides Meunier,1910,管状拟玲虫Tintinnopsis tublosa Levander,1900,长形拟铃虫Tintinnopsis clongata Daday,1887,罗氏拟铃虫Tintinnopsislohmanni(J rgensen,1927)Laackmann,1906,小领细壳虫Stenosemella parvicollis(Marshall,1934)Hada,1935,钟状网纹虫Favella campanula(Schmidt,1901)J rgensen,1924和贪婪铃壳虫Codonella rapa Kofoid&Camp-bell,1929。文章对其形态分类学做了简要描述。

Tintinnid ciliates are an important component of plankton communities and widely distribute in the coastal waters. However, in morphological studies, the tintinnids belonged to the poorly known groups, especially in the water of the South China Sea. In the winter of 2008, the tintinnids sampled from the coastal waters in the South China Sea （Guangdong） were investigated. The water temperature was 17-20℃ and the salinity was about 30‰-1‰. Samples were collected by a horizontal tow net from 1.5 m under the water surface. Part of samples were immediately stored in 4℃ for in vivo observation and the others were fixed in formalin at a final concentration of 5% for future observations of lorica characteristics. The morphological characteristics including lorica features were observed and described by using light microscopical method. In this present study, 16 species were indentified and they belonged to Tintinnopsis, Codonella, Stenosemella and Favella. Three of them were believed to be the first records of China, Codonella apicata Kofoid ＆ Campbell, 1929, Tintinnopsis turbo Meunier, 1919 and Stenosemella expansa Wailes, 1925. In addition, an- other three species were the first records in the semi-tropical and tropical areas of China, Tintinnopsis tubulosoides Meunier, 1910; Tintinnopsis lohmanni （J6rgensen, 1927） Laackmann, 1906, and Codonella rapa Kofoid ＆ Campbell, 1929. The other 10 species included Tintinnopsis beroidea Stein, 1867, Tintinnopsis acuminata （Daday, 1887） Kofoid ＆ Campbell, 1929, Tintinnopsis tocantinensis Kofoid ＆ Campbell, 1929, Tintinnopsis tubulosoides Meunier, 1910, Tintinnopsis tublosa Levander, 1900, Tintinnopsis clongata Daday, 1887, Tintinnopsis lohmanni （J6rgensen, 1927） Laackmann, 1906, Stenosemellaparvicollis （Marshall, 1934） Hada, 1935, Favella campanula （Schmidt, 1901）J6rgensen, 1924, and Codonella rapa Kofoid ＆ Campbell, 1929.
