Remarks.

Vertical distribution within Georgia is recorded from 257 m to 1360 m a.s.l (CJM). The distinct body sizes and proportions observed in specimens from various populations indicate the involvement of not just one, but several locally restricted species. In specific areas, specimens with diverse sizes and proportions coexist, potentially indicating the presence of different species.
