Vipera eriwanensis (Reuss, 1933), known only from the localities of the eastern Aras River in Turkey, was morphologically examined and compared with the related species on the basis of one additional specimen from Gavur mountain (province Gümü?hane), situated outside the known localities. This information changed our knowledge of the total distribution of V. eriwanensis, clearly showing that this taxon has expanded its range at least 210 km to the west in eastern Turkey. Furthermore it differs from V. eriwanensisreported from Turkey, Armenia and Azerbaijan in having a lower number of mid-body scales and loreals,and a higher number of crown scales.
