Popis:	An illustrated description of Boreusyrtis maksimovae gen. et sp. n., a representative of a new genus of Otoplanidae turbellarians (Proseriata) from Lake Baikal, is given. This flatworm shows a peculiar pattern of the ciliated epithelium of the rostral body end, a special morphology of the pharynx and copulative apparatus, and a distinguished topography of the sexual organs. A comparative morphological analysis of the Baikal otoplanid and related forms has allowed us to carry out their partial taxonomic revision, resulting in the isolation of a new genus Boreusyrtis Lukhnev et Timoshkin gen. n., to which, in addition to the endemic species, the morphologically similar species Pseudosyrtis neiswestnovae Riemann 1965 from the Elbe River was attributed. A molecular genetic analysis was carried out for the 18S rRNA gene, based on which a phylogenetic tree was constructed.
