New data on the spider fauna of Urals (Arachnida: Araneae)

Based on new materials, four species are recorded for the fauna of the Urals for the first time. One species, Tegenaria lapicidinarum, found in the open ground exhibition of the botanical garden of Perm State University, is considered as the newest introduced species. Three species: Agyneta suecica, Entelecara flavipes and Neon valentulus have the easternmost points of their ranges in the Trans-Urals. The side-walking spider Runcinia tarabayevi in the forest-steppe Trans-Urals has the northernmost record. Diagnostic characters are illustrated for three little-known species, A. suecica, E. flavipes and N. valentulus. A review of spiders of the Philodromus rufus species group inhabiting in the Urals is given. Of the three species noted in the literature, collection materials confirm the occurrence of two species: P. aryy and P. vinokurovi. Both species are redescribed and illustrated. The records of species P. rufus for the fauna of the Urals needs confirmation.
