厦门沿海的砂壳纤毛虫(原生动物,纤毛门,砂壳目)

TINDINNID CILIATES(PROTOZOA, CILIOPHORA) FROM COASTAL WATERS OFF XIAMEN

对厦门沿海6个代表性站位砂壳纤毛虫进行了为期1年的采集,共分离鉴定了27种砂壳纤毛虫,其中拟铃虫属Tintinnopsis 20种,薄铃虫属Leprotintinnus 3种,类铃虫属Codonellopsis 2种,领细壳虫属Stenosemella 1种以及网纹虫属Favella 1种。对该5属27种砂壳纤毛虫进行形态学描述,并提供了显微照片,其中侧胀拟铃虫Tintinnopsis ventricosoides Meunier,1910为中国新记录种。

Tintinnids are the best known group of marine ciliates and recognized as indicator species of different water masses due to their hard loricae.In the present study,a number of tintinnid species were identified based on samples obtained at six representative sites located in the Bay of Amoy from May 2015 to March 2016.Samples were collected from surface water,concentrated using 20μm mesh,fixed by ethanol(>80%final concentration),and then stored at dark and cool conditions for further analysis.Tintinnids were isolated under a stereomicroscope and the morphological characteristics of lorica were examined under compound light microscope and documented using a charge-coupled device(CCD)camera.Totally,27 species were identified including Tintinnopsis(20 species),Favella(1 species),Stenosemella(1 species),Codonellopsis(2 species),and Leprotintinnus(3 species),respectively.Besides,Tintinnopsis ventricosoides species(Meunier,1910)was believed as the first record in China.Based on their lorica features,all species were here detailed.
