Resumo

The species of the genus Xanthorhoe (Hübner, 1813 [“1796”]) of the incursata group from the Asian part of Russia are considered: X. pseudoannotinata Vasilenko, 2007, X. uralensis Choi, 2003, X. elenae Vasilenko sp. n., X. sajanaria (Prout, 1914), and X. derzhavini (Djakonov, 1931). The species status of X. pseudoannotinata stat. resurr. is restored. The taxon X. sajanaria djakonovi Vasilenko, 1995 is synonymized with the nominative subspecies X. sajanaria sajanaria (Prout, 1914). The scope and diagnosis of the subspecies X. derzhavini jakuta Vasilenko, 1995 are reconsidered. The diagnostic features of and an identification key to the species based on the male and female genitalia are given. Peculiarities of the distribution and biology of the Palaearctic species are reviewed. Morphological species subgroups within this group and the probable centers of the origin of species are discussed.
