摘　　要：采用Giemsa染色及活体观察方法,显示并描述了采自重庆北碚地区中华蟾蜍指名亚种Bufo gargarizans gargarizans肠道内的卵形后线虫Metanema ovula sp.nov.,切断沟滴虫Petalomonas abscissa(Dujardin,1841)Stein,1859和蛙毛线虫Trichomitus batrachorum(Perty,1852)等3种异养鞭毛虫的形态及其鞭毛、核器等结构的特征。Three species of heterotrophic flagellates （ Eugtenida, Trichomondida ）, which habit in the intestine of the toad, Bufo gargarizans gargarizans, found from Chongqing of China, were described Metanema ovula sp. nov. , Petalomonas absdssa （ Dujardin, 1841 ） Stein, 1859 and Trichomitus batrachorum （Perty, 1852）. Based on observations under a compound microscope equipped with differential interference contrast （DIC） both in vivo and impregnation using Giemsa＇s stain, detailed descriptions of morphology for new spedes are presented.Metanema ovula sp. nov. （Figs. 1-2, 7, 10） Type-locality. Chongqing （29°5＇N, 106°5＇E）,China. Date of sampling. Apr. 2006. Type-deposition. Holotype （ CQ-20060401-01 ） and paratype （CQ-20060402-02） are deposited in the collection of The Key Laboratory of Animal Biology in Chongqing, Chongqing Normal University, China. The diagnosis of Metanema ovula sp. nov. （Number of measured specimens： 24）： body is oval or spindly with smooth peUicle in shape; the shape of the body is immutable; there is no concave of the ventral. Measures of body are 13.6μm （11.2-20.0） in length, 8.8 μm （7.5-10.5） in width, flagellum 21.3μm （14.3-23.9） long.
