Four species of Trichodina parasitizing the gills of cultured molluscs and fishes in China are described: Trichodina pectenis Stein, 1974 from the scallop Mizuhopecten yessoensis; Trichodina jadranica Raabe, 1958 from the fishes Mugil cephalus and Anguilla bicolor bicolor; Trichodina acuta Lom, 1961 and Trichodina rostrata Kulemina, 1968 from the fish Acrossocheilus fasciatus. The description of T. pectenis presented here first includes both live characters and morphometric data obtained from specimens impregnated using the wet silver nitrate and protargol methods. The other species were revealed by the dry silver nitrate method. Intensities of infestation and comparisons with related species and populations are provided for each of the four.
