At present specialists consider forest-steppe subspecies (Marmota baibacina kastschenkoi) of a gray marmot (M. baibacina) the separate species (M. kastschenkoi). There is appears the question about the character of the spatial relationship between these two forms. There is no accurate data on this point in the literature, at the same time, there is the information about the zones of the contact and hybridization of M. baibacina with other morphologically similar to them species - M. bobak and M. sibirica. Based on the review of the literature, we have revealed the territory between the areas of the two investigated forms for which there is no any information about the taxonomic status and landscape-biotopic distribution of the marmots inhabiting it. The investigation of this region made it possible to establish the territorial gap between the borders of the areas of these two species, the reason of which is the ecology-geographical factor. Basing on the results of the morphological analysis of the mammals of the mentioned region we established their belonging to the species of M. kastschenkoi and the southern bound of its distribution.
