- Abstract
The prosobranch snail Lithoglyphus naticoides (C. Pfeiffer, 1928), originated from the Ponto- Caspian region, was collected in the river Nemunas in Lithuania. The diversity of intramolluscan stages of trematodes associated with L. naticoides was examined. A total of nine species of trematodes were detected in the population studied - cercariae of Apophallus muehlingi (Jägerskiöld, 1899) (dominant species), Xiphidiocercaria sp. 1 of Odening (1971), Xiphidiocercaria sp. 2 of Odening (1971), Sanguinicola sp., Palaeorchis sp., Notocotylus sp., Crowcrocaecum skrjabini (Iwanitzky, 1928) and Spelotrema sp. metacercariae. Intramolluscan stages of echinostomatid trematode as endosymbionts of L. naticoides were found for the first time. Red-tailed gigantocercous cercaria, according to the main features of morphology - a discernible collar without collar spines, two subequal suckers, excretory ducts with 8-10 large composites (from 2-3 granules) and 3-4 small irregular concretions, a double excretory vesicle and 16 flame cells were identified as echinochasmid and attributed to the genus Echinochasmus Dietz, 1909.
