An illustrated description of Boreusyrtis maksimovae gen. et sp. n., representative of a new genus of Otoplanidae turbellarians (Proseriata) from Lake Baikal, is given. The worm shows a peculiar pattern of the ciliated epithelium of the rostral body end, the special morphology of the pharynx and copulative apparatus, and the distinguished topography of the sexual organs. A comparative morphological analysis of the Baikal otoplanid and related forms has allowed us to perform their partial taxonomic revision, resulting in the erection of Boreusyrtis Lukhnev et Timoshkin gen. n. Pseudosyrtis neiswestnovae Riemann 1965, from Elba River, closely related to our new species, is also transferred to the new genus, comb. n. A molecular analysis, based on 18S rRNA gene sequence data, has also been performed, and a phylogenetic tree constructed.
