The full list of parthenogenetic larvae and cercaria is presented for the first time for the freshwater snail L. saridalensis (Gastropoda, Pulmonata), which inhabits the watershed area of Chany Lake. It was found that this snail species plays a significant role as the first intermediate host in the life cycles of trematodes in the southern part of Western Siberia. The invasion parameters were calculated for different parasite species. It was found that 50% of the L. saridalensis population serves as the first intermediate host for eleven trematode species that belong to six families: Plagiorchiidae, Echinostomatidae, Diplostomatidae, Strigeidae, Notocotylidae, and Schistosomatidae. The prevalence of infection by each trematoda species in L. saridalensis was determined. Five species of trematodes from the Plagiorchiidae and Echinostomatidae families formed the center of the parasite community, viz., the species Plagiorchis elegans, P. mutationis, Opisthioglyphe ranae, Molinella anceps, and Echinoparyphium aconiatum. Two species, Plagiorchis mutationis and P. multiglandularis, were recorded in the studied area (the Chany Lake watershed area) for the first time at the stages of parthenite and cercaria. It was also found that 1% of L. saridalensis population have multiple (mostly two-species) infections.
