ABSTRACT. Based on abundant fresh and re-examined samples from the Asian part of Russia, the distributions of eleven anthropochore oniscid species have been clarified. Both the genus Oniscus Linnaeus, 1758 and the species O. asellus Linnaeus, 1758, as well as the family Oniscidae they belong to, are new to Asia. Both the genus Styloniscus Dana, 1852 and the species S. mauritiensis (Barnard, 1936), as well as the family Styloniscidae they belong to, are new to Russia. Both the genus Parcylisticus Verhoeff, 1943 and the species P. dentifrons (Budde-Lund, 1885) are recorded from Asian Russia for the first time. The first regional records of woodlice include seven species for the Krasnoyarsk Krai, three species each for the Republic of Khakassia and the Sverdlovsk Oblast, two species each for the Tyumen and the Jewish Autonomous oblasts, and a single species for the Kurgan Oblast. Three more species are also reported from the Chelyabinsk Oblast, two more species from the Altai Krai, as well as one more species from the Primorskii Krai. Armadillidium nasatum Budde-Lund, 1885 and Trichoniscus pygmaeus Sars, 1898 are excluded from the species list of terrestrial isopods of Asian Russia. The distributions of 11 species encountered are mapped within the study area. An identification key to known species of Oniscidea from the Asian part of Russia is given for the first time.
