The role of Siberia as a barrier for dispersal of both Diplocephalus and Savignya is displayed nowadays in the isolation not only of Europe and Manchuria from each other, but also of both of them from the Nearctic. Only 3 species have been recorded from North Arne rica: S. birostrum

, D. subrostratus

, and D. cristatus cristatus. None of them is endemic there, while D.c. cristatus (reported also from New Zealand) seems to have been introduced by man. As another argument in favour of the above hypothesis implying the faunal connection between Europe and Manchuria to have been established due to a direct pathway through boreal Siberia may be quoted the complete absence in the genera under study of Euro-Manchurian disjunctions relatively common in spiders (s. ESKOV 1987). REFERENCES CHAMBERLIN, R.V. et IVIE, W. (1947): The spiders of Alaska. - Bull. Univ. Utah, 37(10): 1-103. CROSBY, CR. et BISHOP, S.C.
