Abstract: | During parasitological surveys in Chongqing, China, three trichodinids infecting a freshwater fish, Misgurnus anguillicaudatus (Cantor), and a mollusc, Anodonta woodiana (Lea), were investigated. Two of these species were found to be new. Trichodina lechriodentata n. sp., from the fish, was identified by its small-sized body and irregularly rectangular blade, while T. rara n. sp., from the mollusc, is characterised by its overall dimensions, denticle morphology and the presence of a white speckle in some specimens. T. modesta Lom, 1979 is also described from the fish. Photomicrographs and morphometric data are presented for all of the species. |
