Abstract
The information about the northern range boundary of the steppe-runner Eremias arguta (Pallas, 1773) has changed in recent decades. Based on the reliable recordins in 2001-2020 from 12 locations the northern range boundary between Volga and Ural was specified. It runs through the Engelsky District of the Saratov Region, through the Stavropolsky, Kinelsky, Bogatovsky and Borsky Districts of the Samara Region, through the Buzuluksky and Tashlinsky Districts of the Orenburg Region of Russia. The northern limit of the range should be considered the Volga above-floodplain slope in the left-bank part of the Stavropolsky district in Samara region. All specimens encountered had body coloration typical of Eremias arguta deserti (Gmelin, 1789). The locations of steppe-runner are confined to open spaces treeless and without a dense herbaceous vegetation on the southern sandy slopes.
