Morphological and molecular data on Shimazu, 1974 (Digenea: Microphalloidea: Zoogonidae) ex (Günther, 1877) and taxonomic problems in Zoogoninae genera.

New morphological and molecular data were generated for trematodes recovered from the intestines of the fish from two locations in the south of the Russian Far East. Morphologically, these trematodes are identical to (Microphalloidea: Zoogonidae) from Japan. According to results of phylogenetic analysis based on 28S rDNA sequence data, was closely related to , and appears as a sister taxon to these two species.

(Seo, Rim, Lee, 1964) sensu Pyo , 2014 (Trematoda: Diplostomidae Poirier, 1886): morphology, life cycle, and phylogenetic relationships.

Furcocercariae of the genus Railliet, 1919 (Diplostomidae Poirier, 1886) were found in freshwater snails Starobogatov, 1957 (Planorbidae Rafinesque, 1815) collected from three localities in the Russian southern Far East. For the trematodes from each locality, frogs played the role of the second intermediate host, and rats were the definitive host. Chickens were insusceptible to infection.

nom. nov., other spp. and in East Asia: morphology, molecular data and phylogeny within Echinostomatidae.

Life cycles, and morphological and molecular data were obtained for Echinostoma chankensis nom. nov., Echinostoma cinetorchis, Echinostoma miyagawai and Isthmiophora hortensis from East Asia.
