In this work genetic diversity and distribution of the E. velox collected in the Urals and Western Siberia of the Russian Federation were investigated in comparison with that, of the European populations. Analysis of the CO1 gene region showed that the studied populations from the Urals and Western Siberia differ significantly from the European ones and represent a separate genetic line. However, the nuclear nITS and 18SrRNA genes, as well as the results of morphological analysis, did not show such isolation of the Trans-Ural populations from those, in Europe. As in many studies on E. velox, we found atypical structural features of the fifth prosomal leg among females in Ob Bay. The CO1 shows that the divergence of genetic lines occurred approximately in the Middle Pleistocene, and the species itself is Paleogene–Neogene by origin.
