Pelodytes caucasicus occurs in all four Colchis refugia. with forest and meadow formations of the Colchis type, makes it possible to identify three more regions in the Caucasian Isthmus, besides the Western Caucasus (the Colchis proper), in which the Colchis herpetofauna occurs. The three regions are: the Bjelo-Labinskij region on the northern slope of the Western Caucasus, the Kakhetinskij (Lagodekhi-Zakataly) region on the southern slope of the Eastern Caucasus, and the Borzhomskij region in Eastern Transcaucasia (Fig. 10). The comparative composition of the herpetofauna of these regions is shown in Table 1. It is evident from Table 1, that the most significant differences are found between the Colchis and the Kahetinskij regions and the least significant differences are between the Colchis and the Borzhomskij and the Belo-Labinskij regions. Taking into account the above mentioned peculiarities of distribution of herpetofauna within the Colchis refugium itself, the differences become even less significant. In this case, we deal with three regions smaller in space, and a wealth of species of the Colchis herpetofauna that occur in refugia and have survived off the main territory of the Colchis. The Belo-Labinskij region is only conventionally separated from the Colchis by the crest of the Main Caucasian Mountain Range. All the northern Colchis species, except L. a. grusinica, occur on the northern slope of the Western Caucasus in the Belaja and the Small Laba river drainages. It should be stressed that this unity is based on the fact that the characteristic Colchis elements of flora and vegetation cross over the Main Caucasian Range in the place known as "the Colchis Gates" to its northern slope.
