Year: 2025, Number: 4, Pages: 12-16

In the southern Russian Far East, cercariae of the genus Diplodiscus possessing horn-like projections on the tegument surface were discovered in the mollusks Gyraulus centrifugops. Morphometric and molecular genetic data were obtained for these cercariae. Based on this analysis, the trematodes were identified as belonging to the species Diplodiscus mechrai. Possible reasons for the emergence of these tegumental projections, which are atypical for cercariae of the genus Diplodiscus, are discussed.
