ABSTRACT: Recent (2017) calculations of spider species richness in the boundaries of Russia and other former Soviet Union republics, as well as between physiographical regions of these territories, are provided in comparison with earlier data. By December 31st, 2017, 3437 and 2445 spider species were reported from the FSU territories and Russia, respectively. A prediction for a spider species richness of the FSU and Russia is given. 39 spider species lists of both the post-Soviet republics and physiographical regions are provided as electronic supplementary data.
KEY WORDS: Araneae, diversity, spiders, post-Soviet republics, physiographical regions, fauna, catalogue.
