ABSTRACT: Fifty-five species of spiders were collected in the Oymyakon area (ca 64.5–65°N, 142–145°E), eastern Yakutia, 2003. The vast majority of species found are boreal and hypoarctic spiders. The material include some steppe species, e.g. Zelotes baltistanus Caporiacco, 1935, Pellenes gobiensis Schenkel, 1936 and P. limbatus Kulczyński, 1895, at the northern limits of their range. Haplodrassus pugnans (Simon, 1880), Micaria lenzi Bцsenberg, 1899, Philodromus alascensis Keyserling, 1884, Chalcoscirtus glacialis sibiricus Marusik, 1991 and Xysticus baltistanus (Caporiacco, 1935) are xerothermic species found here in northern “cold steppes”. Three species, Euryopis saukea Levi, 1951, Pellenes gobiensis and Thanatus tuvinensis Logunov, 1996 are new to Yakutia. The distribution patterns of the species found as well as of five previously reported species are discussed.
