Abstract
Three species of freshwater fishes were examined for ectoparasitic trichodinids in Chongqing,China.Trichodinids belonging to three genera,TrichodinaEhrenberg,1830,Trichodinella(Raabe,1950)Sramek-Husek,1953 and TripartiellaLom,1959,were investigated.One species,Trichodina obtusiformissp.nov.was isolated from the gills of cultured Aristichthys nobilis.The other four known species,Trichodina acutaLom,1961,Trichodina nobilisChen,1963,Trichodinella epizootica(Rabbe,1950)Sramek-Husek,1953 and Tripartiella macrosomaBasson Van As,1987,were reinvestigated.This is the first record from China for both Trichodina acutaand Tripartiella macrosoma.
