Five new species are described: Dras- 57 in the steppe zone of the Urals contained numerous syllus sur sp.n. (#$), Micaria gulliae sp.n. (#$), poorly known, and some new species. The main aim of Zelotes fallax sp.n. (#), Zelotes occultus sp.n. (#), this paper is to (re)describe some rare and some new Z. orenburgensis sp.n. (#$). Haplodrassus minor (O. species based on the Urals material. We also present new Pickard-Cambridge, 1879) is redescribed from the Urals locality data, and thus refine our knowledge of the material.
