The morphology of <jats:italic>A. anastasii<\/jats:italic> n. sp. corresponds to that of <jats:italic>Allocreadium<\/jats:italic> sp. from Lake Khar (Mongolia) and <jats:italic>Allocreadium<\/jats:italic> sp.

Genetic analysis revealed the identity of <jats:italic>A. anastasii<\/jats:italic> n. sp. to <jats:italic>Allocreadium<\/jats:italic> sp. 1 from the Nezhinka River and Lake Khar. <jats:italic>Allocreadium macrolecithum<\/jats:italic> n. sp. was differentiated from Palaearctic <jats:italic>Allocreadium<\/jats:italic> spp. by having the following features: respectively large vitelline follicles extending from posterior extremity to anterior margin of the ventral sucker; relatively short caeca reaching the border of middle and posterior thirds of hindbody; and small testes in the middle of hindbody. Interspecific genetic p-distances between <jats:italic>Allocreadium<\/jats:italic> spp. were 0.16\u20137.23% in 28S gene and 18.62\u201331.54% in <jats:italic>Cox1<\/jats:italic> mtDNA gene. In the phylogenetic tree reconstructed with Maximum parsimony and Bayesian Inference methods, <jats:italic>A. anastasii<\/jats:italic> n. sp. and <jats:italic>A. macrolecithum<\/jats:italic> n. sp. were nested into different species groups of the genus <jats:italic>Allocreadium<\/jats:italic> \u2013 sister to <jats:italic>A. khankaiense<\/jats:italic> and <jats:italic>A. bursense<\/jats:italic>, respectively.
