The article describes the structure and seasonal dynamics of spider species diversity in bilberry and mossy pine forest in the republican reserve “Pribuzhskoe Polesie”. 51 species had been registered in the bilberry pine forest and 52 species in the mossy pine forest. In total, 71 species which belong to 17 families had been registered. 53 new species for the territory of the reserve and one new species for Belarus are indicated. Studies have shown that the species diversity of spiders has a similar structure, which is confirmed by the results of calculating the Shannon, Pielu, Simpson and Margalef indices. In the bilberry pine forest, the number of individuals and the dynamic density are higher, while in the mossy pine forest there is evenness and species richness. The dominant species in the mossy pine forest is Trochosa terricola (relative abundance 25.0 %), in the bilberry pine forest there are two dominants - Alopecosa aculeata and T. terricola (30.3 and 23.5 %, respectively).
