Morphological and molecular data for two species (Trematoda: Plagiorchiidae) from the southern Far East of Russia.

Adult trematodes of two species of the genus were found in the southern Far East of Russia: one species in the intestine of a naturally infected Japanese large-footed bat () and the other in a golden hamster () experimentally infected with metacercariae collected from a stonefly. On the basis of morphological and molecular studies, the trematode individuals found in the bat were identified as , which confirms that this species is cosmopolitan. The trematodes reared in the hamster were similar in their morphological features to the European However, due to the lack of nucleotide sequences for this species from the type region, the southern Far East of Russia trematodes, found in this study, were provisionally designated as In addition, the phylogenetic reconstruction based on a mitochondrial marker revealed inconsistency of the data obtained from cercariae diagnosed as a single species, Our data also indicate that the specimens available in the NCBI database referred to as and belong to the same species.

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.
