A total of eight species of furcocercous cercariae of four families (Strigeidae, Diplostomidae, Schistosomatidae and Sanguinicolidae), were found in 2005 in Lake Konnevesi in Central Finland in four snail species (Valvata macrostoma, Lymnaea stagnalis, Bathyomphalus contortus and Planorbarius corneus). Australapatemon burti (Miller, 1923), Australapatemon sp., Cotylurus brevis Dubois et Rausch, 1950, Cercaria spinulosa Ginetsinskaya, 1959 and Sanguinicola sp. are new species records for Finland. Ichthyocotylurus variegatus (Creplin, 1825) and Bilharziella polonica (Kowalewski, 1895) were first recorded as cercariae in Finland. The most common cercariae were A. burti (prevalence 13.3%) and Diplostomum pseudospathaceum Niewiadomska, 1984 (10.0%). Our study represents the first host record of Valvata macrostoma for larval stages of Australapatemon sp. and Sanguinicola sp.

Nine species of larval flukes, Notocotylus attenuatus, Echinostoma revolutum, Echinoparyphium aconiatum, Hypoderaeum conoideum, Plagiorchis elegans, Diplostomum pseudospathaceum, Australapatemon minor, Cotylurus sp., and Trichobilharzia ocellata were found in Lymnaea stagnalis in lake Kuuhankavesi (central Finland). Two species, P. elegans and E. aconiatum, are a new records from Finland and L. stagnalis was recognized as proper host for H. conoideum. In comparison with the records of Wikgren (1956) who found ten species of cercariae in L. stagnalis from the Tvärminne archipelago, our investigations revealed only five of these species: N. attenuatus, E. revolutum, D. pseudospathaceum (correct specific name for Wikgren’s D. spathaceum), Australapatemon minor (correct generic and specific names for Wikgren’s Apatemon gracilis) and T. ocellata. After Wikgren’s study on Tvärminne archipelago and Väyrynen from Northern Finland, the lake Kuuhankavesi (central Finland) are the third locality in Finland where larval trematodes have been studied.
