Abstract. This paper contributes to global biodiversity research. Recent (2011) calculations of the spider species richness in Russia and the former Soviet Union republics, as well as in physiographical regions, are provided in comparison with earlier data. By 31st December 2011, 3,296 and 2,339 spider species have been reported from the FSU territories and Russia, respectively. An updated forecast on the expected spider diversity in the FSU and Russia faunas is given.
