Resumo

Based on male material collected from the Cis-Urals steppe, two new species, are diagnosed, described and illustrated: Drassyllus borlynensis sp. n. and Walckenaeria danismani sp. n. A map showing the collecting localities are provided for Walckenaeria danismani sp. n. Drassyllus borlynensis sp. n. differs from the most similar D. praeficus (L. Koch 1866) and D. villicoides (Giltay 1932) in the smaller size, body colouration and the conformation of the male palp. Walckenaeria danismani sp. n. belongs to the subgenus Prosopotheca Simon 1884, where it appears to be most similar to W. baborensis Bosmans 1993, yet differing in the shape of the embolus.
