A complete list of 132 spider species collected by D.E.Kharitonov's expedition to Zaisan Lake in July-August 1936 is provided, with 31 species being recorded from East Kazakhstan Area (EKA) for the first time.Distribution of all species new to EKA is discussed.Six species are described as new: viz., Alopecosa zaisanica sp.n.(male), Gnaphosa oirat sp.n.(female), Pardosa kalba sp.n.(female), P. сharitonovi sp.n.(female), P. kurchum sp.n.(female) and Robertus ovsyannikovi sp.n.(female).Two species from this collection -Drassodes cupa Tuneva, 2004 and Micaria seymuria Tuneva, 2004 -were described earlier.One species is synonymized: Drassodes charitonovi Tuneva, 2004 syn.n.= D. neglectus (Keyserling, 1887).Yet, data on additional 17 species from other collections, of which six species have been recorded from West Kazakhstan for the first time, are provided.Based on the results of the present study, the total number of spider species recorded from EKA has increased to 476 species in 186 genera and 26 families.How to cite this paper:
