摘　　要：对采自山东、广东和香港沿海的八种盾纤类纤毛虫:冠帆口虫、维亚可夫帆口虫、蠕形康纤虫、贪食迈阿密虫、异海洋尾丝虫、中华后阿脑虫和两种蟹栖异阿脑虫相似种进行了形态学研究。其中,中国南海新记录种维亚可夫帆口虫种群与Wang,et al.所描述种群以及中华后阿脑虫新种群与Song&Wilbert记述的青岛种群和南极种群相比,在个体大小和体动基列数目上均有所差异;贪食迈阿密虫潍坊种群的体动基列恒为12列,与Song&Wilbert的报道有较大差异。两种异阿脑虫与蟹栖异阿脑虫在口纤毛器结构和体形上完全相似,但在体动基列数目上有明显差异,因数据不足,暂定为蟹栖异阿脑虫相似种。Free-living scuticociliates are common inhabitants of littoral and sandy habitats,some of which are faculta-tive histophagous parasites in marine fish.Therefore,it is very important to recognize and study those ciliates.However,the distribution,especially in South China Sea and the species inventory of this group are still limited.This study aims to supply new information to this group from both the northern and southern China seas.Eight marine scuticociliates: Pleuronema coronatum Kent,1881,Pleuronema wiackowskii Wang et al.,2008,Cohnilembus verminus Müller,1786,Miamiensis avidus Thompson & Moewus,1964,Uronema heteromarinum Pan et al.,2010,Metanophrys sinensis Song & Wilbert,2000 and two species of Mesanophrys cf.carcini,were morphologically investigated by using live observa-tion,portargol impregnation and silver nitrate impregnation methods.Pleuronema wiackowskii,the new record for the South China Sea,had wider ranges of body size and higher number of somatic kineties than the original Qingdao population.Uronema heteromarinum,the population obtained from the South China Sea,was similar to the Qingdao popula-tion reported by Pan et al.(2010).Metanophrys sinensis,obtained from an aquafarm of Weifang,Shandong Province,deferred from previous investigations in body size and the number of somatic kineties.The population of Miamiensis avidus,also obtained from the same aquafarm,had stable 12 somatic kineties,which was different from the reports of Thompson & Moewus(1964)(10—13),Dragesco et al.(1995)(13—14) and Song & Wilbert(2000)(13—15).Two forms of Mesanophrys,collected from coastal area of Qingdao and Hongkong respectively,owned stable number of somatic kineties,which were different from the well-konwn Mesanophrys carcini.Considering this insufficient evidence they were defined as Mesanophrys cf.carcini preliminarily.The populations of Pleuronema coronatum and Cohnilembus verminus,which respectively collected from the coastal water of Guangdong and the aquafarm of Weifang,corresponded well with previous inv
