Abstrakt: A Leucochloridium sp. Carus, 1835 sporocyst with a mature colored broodsac was found in a Succinea putris L., 1758 snail in the Boksitogorsk district of Leningrad Region (Russia). The pigmentation of the sporocyst's broodsac was different from those of other Leucochloridium Carus, 1835 species previously described for Europe. The obtained sporocyst is most similar by the coloration of its broodsac to the trematodes of the same genus from Japan. The genotyping of the investigated sporocyst by the rDNA gene fragments (complete ITS1, ITS2, 5.8S and partial 18S and 28S sequences) was conducted. Genetic distances between the obtained sporocyst and the previously described species of the genus Leucochloridium were higher than intraspecific ones in the most cases. These data and the data of morphological analysis imply that the investigated sporocyst belongs to a separate species of the Leucochloridium genus, previously not described in the European region.
