The distribution range is stretched along the Black Sea coast, covering the forested foothills of the Caucasus up to 900m asl, from the settlement of Khopa in Turkey and Suramsky pass in the east across Colchis up to Mikhailovsky pass in the west. From here the species ranges to the northern slope of the Great Caucasus. Populations are found along the foothills up to the settlement Ubinskaya in the west, to the town Maikop in the north and to the mouth of the Urushten River in the east. In general, the distribution is divided into two parts, Ajaro-Lazistan (Turkey and Ajaria) and north-Colchis (western Georgia, Abkhazia and the Krasnodar Territory of Russia).
