The main refugia of the endemic Colchis herpetofauna. Mountain ranges underwent substantial glaciation (Grozdetskiy 1954; Markov et al. 1965). The main center of dispersal of these species was the Colchis, where relatively heat-loving vegetation of the Caucasian type survived even during the periods of the extreme Pleistocene cooling (Vereschagin 1958; Adamyants 1971). Along with the Colchis, smaller refugia sporadically survived on the territory of the Caucasus Black Sea coast, and also on the northern slope of the Main Caucasian Range between the Pshekha River and the Small Laba River. The present distribution of the Tertiary vegetation of the Colchis type in the western Caucasus testifies to this (Kharadze 1974; Pechorin and Lozovoy 1980; Kholyavko et al. 1978; Adamyants 1971; Koval and Litvinskaya 1986). It was in the narrow humid gorges with a relatively constant thermal regimen that the representatives of the Colchis group remained intact. At the same time, independent populations might also have been preserved in mid-mountain areas where refugia of the Colchis vegetation exist in the vicinities of the Fisht-Oshtenskij Mountain Massive, the Lagonaki Plateau and even in the Central Caucasus (Kholyavko et al. 1978; Kharadze 1974). Small refugia seem to have also remained on the southern slope of the eastern pan of the Greater Caucasus and in the Kuru River Gorge. It is indisputable that the majority of the mountainous populations of Colchis species perished during the Pleistocene and.
