Abstract

Fifty-three species of spiders and one species of harvestmen were found in the previously unstudied Gydansky Peninsula, northwestern Siberia. Distribution for each species is given. Records of certain species are of a special interest: Xysticus viduus (the northernmost locality in its range), Crosbylonia borealis (the westernmost), Oreoneta eskovi (the northernmost and the westernmost), Clubiona norvegica (the easternmost in Asia), Pachygnatha listeri , Helophora insignis and Mitopus morio (the northernmost in Asia) and Oreoneta leviceps (the southernmost in the Palaearctic). Three species, Oreoneta eskovi, Pardosa oljunae and Thaleria orientalis, are endemics of West Siberia. About two-thirds of the species are either circum-Holarctic or trans-Palaearctic.
