对采自重庆地区寄生于鲢、鳙及草鱼鳃上的5种外寄生车轮虫进行了形态学及分类学研究,其分别隶属于:车轮虫属、小车轮虫属及三分虫属,其中包含1新种和中国2新纪录。即钝圆车轮虫Trichodina obtusiformissp . nov .,急尖车轮虫T. acutaLom,1961,显著车轮虫T. nobilisChen ,1963,周丛小车轮虫Trichodinella epizootica( Rabbe ,1950)Sramek-Husek ,1953和大型三分虫Tripartiella macrosomaBasson & Van As ,1987。文中对新种进行了详细的描述并提供了新种及已知种的附着盘银染标本之显微照片及齿体线条图。
Three species of freshwater fishes were examined for ectoparasitic trichodinids in Chongqing, China. Trichodinids belonging to three genera, Trichodina Ehrenberg, 1830, Trichodinella （Raabe, 1950） Srarnek-Husek, 1953 and Tripartiella Lore, 1959, were investigated. One species, Trichodina obtusiformis sp. nov. was isolated from the gills of cultured Aristichthys nobilis. The other four known species, Trichodina acuta Lore, 1961, Trichodina nobilis Chen, 1963, Trichodinella epizootica （Rabbe, 1950） Srarnek-Husek, 1953 and Tripartiella macrosoma Basson ＆ Van As, 1987, were reinvestigated. This is the first record from China for both Trichodina acuta and Tripartiella macrosoma.
