Metagonimus suifunensis sp. n. (Trematoda: Heterophyidae) from the Russian Southern Far East: Morphology, life cycle, and molecular data.
The trematode from the Russian Southern Far East, earlier defined as M. yokogawai Katsuradai, 1912, was determined as a representative of the new species Metagonimus suifunensis sp. n. The life cycle of this trematode was experimentally studied and morphometric data for the cercariae, metacercariae and adult worm stages were obtained. The molecular data for samples from six Russian localities were received using the ITS1-5.8S-ITS2 region and 28S gene nuclear ribosomal DNA. The results revealed that M. suifunensis sp. n. does not have significant morphometric differences with M. yokogawai, M. takahashii and M. miyatai. However, the new species validity was confirmed by the molecular data. The phylogenetic relationship analysis of Metagonimus representatives showed that M. suifunensis sp. n. is well-differentiated specie with low variability in the whole area.
