Аннотация

Information on the distribution and typical biotopes of slugs of the genus Arion in Western Siberia is provided. New localities of A. fasciatus (Nilsson 1823) have been recorded, of which one is a natural biotope located beyond the urban area. The A. subfuscus s. l. complex of cryptic species is represented by only A. fuscus (Müller 1774) individuals of which occur in the subzones of the middle and southern taiga, as well as in aspen/birch forests. A. sibiricus Simroth 1901 is found in the southern taiga subzone.
