There are 40 spider species from 13 families were collected by the Barber pitfall traps in the steppe ravine in Osokorovka Village (Novovorontsovsky District, Kherson Region, Ukraine). The maximal species richness registered for the families Gnaphosidae (14 species), Lycosidae (10 species) and Thomisidae (7 species). A biotope in the bottom of the ravine was characterized by the maximal species richness, the maximal number of specific species and the maximal dynamic density. This biotope serves as a refuge for mesophilous species. The spider community composition in this biotope was significantly different from surrounding steppe habitats.
