On Acantholycosa solituda (Levi ^|^amp; Levi) and A. sterneri (Marusik) (Araneae: Lycosidae), a pair of geographically distant allied species

Abstract

The wolf spider species Pardosa solituda Levi & Levi (Nearctic: Rocky Mountains) and Pardosa sterneri Marusik (Palearctic: Mongolia, South Siberia) are redescribed and illustrated, the female of the latter described for the first time. The two species are closely allied by the conformation of the copulatory organs. The males share the condition of having a lanate pubescence on the tibiae and metatarsi of the first and second legs. The cuticle of these leg segments is equipped with an abundance of pores of a type presumably associated with excretion of some semiochemical substance. Both species are here transferred to the genus Acantholycosa.
