A survey of the East Palaearctic Lycosidae (Araneae). 9. Genus Xerolycosa Dahl, 1908 (Evippinae)

Three species of Xerolycosa: X. nemoralis (Westring, 1861), X. miniata (C.L. Koch, 1834) and X. mongolica (Schenkel, 1963), occurring in the Palaearctic Region are surveyed, illustrated and redescribed. Arctosa mongolica Schenkel, 1963 is removed from synonymy with X. nemoralis and transferred to Xerolycosa, and the new combination Xerolycosa mongolica (Schenkel, 1963) comb. n. is established. One new synonymy, Xerolycosa undulata Chen, Song et Kim, 1998 syn. n. from Heilongjiang = X. mongolica (Schenkel, 1963), is proposed. In addition, one more new combination is established, Trochosa pelengena (Roewer, 1960) comb. n., ex Xerolycosa
