Identification of a new species of von Nordmann, 1832 (Monogenoidea Gyrodactylidae) isolated from in Yarkand River, Xinjiang, China.

To investigate infection of fish in the river system of Xinjiang (China), individuals were isolated from specimens of . Morphological characterization and phylogenetic analysis based on rDNA locus revealed that the gyrodactylids belong to new species. n. sp. differs significantly in the morphology of the haptoral structures from 12 known species of found in fishes of the subfamily Schizothoracinae. In particular, n. sp. has a relatively short dorsal bar with thick and large ends, flat and straight hamuli roots, and small ventral bar processes. Furthermore, . n. sp. is the only representative of found on Using the BLASTn search of rDNA sequences in GenBank and the Bayesian Information and Maximum Likelihood methods, we constructed phylogenetic trees for n. sp. As a result, our studies clearly identified that n. sp. was the first monogenean isolated from . and a new species belonged to the subgenus .
