Trematodes with diagnostic criteria inherent to Asymphylodorinae were found in the intestine of Carassius gibelio from the south of the Russian Far East. Results of 28S rDNA-based phylogenetic analysis showed that the worms belong to Parasymphylodora and are closely related to P. lacustris. The genetic distance value of 4.52±0.71% between these trematodes corresponds to the interspecific differentiation level for Lissorchiidae. Our discovered trematodes differ from both P. lacustris and other Parasymphylodora species based on a number of morphometric criteria. Based on these results, they were accepted as a new species of the genus Parasymphylodora, named P. jugiformis sp.n. The results of the phylogenetic analysis based on 28S rDNA sequence data confirmed the presence of several clades of the generic level within Asymphylodorinae. The molecular characters for the diagnosis of these clades as hypothetical genera are proposed.
