New records of A. fasciatus, A. fuscus and A. sibiricus are given from western Siberia. Arion fasciatus lives in the city of Tomsk, but it has also been found in a natural habitat for the first time. Only A. fuscus from the A. subfuscus s. l. complex has been recorded, inhabiting the subzones of aspen-birch forests, middle and southern taiga, whereas A. sibiricus is confined to the subzone of southern taiga.
