摘　　要：在重庆地区鱼类寄生虫的调查过程中,从淡水鱼泥鳅的鳃上获得四种外寄生车轮虫,经鉴定隶属车轮虫科(Trichodinidae)、车轮虫属(Trichodina),含1车轮虫未定种Trichodina.sp.和3已知种,即:适度车轮虫(Trichodina modesta Lom,1970),斜齿车轮虫(Trichodina lechriodentata Zhao & Tang,2007)及拟黑色车轮虫(Trichodina paranigra Tang et al,2005)。车轮虫的形态学特征统计采用Lom(1958)倡导的统一特定方法,齿体的定位描述则采用Van As & Basson(1989)和Tang,Zhao & Chen(2005)改进的方法进行。In the survey of fish parasites in Chongqing area, four species of epizoic trichodinid were found in the gills of freshwater fish loaches and they were identified to be Trichodinidae family and Trichodina genera,i.e.an indefinite species （Trichodina.sp.） and three known species （Trichodina modesta Lom, 1970; Trichodina lechriodentata Zhao ＆ Tang, 2007; Trichodina paranigra Tang et al, 2005 ）. Morphological taxonomy ofepizoic trichodinid ofloaches was statistically analysed with unified and specific method proposed by Lom （ 1958）; The location of denticles was described with the improved methods of Van As ＆ Basson （1989） and Tang, Zhao ＆ Chen（ 2005 ）.
