Аннотация: In Russia, Myotis nattereri was considered as a monotypic species, of which its range is divided into two parts.. One ofthem is the northern fragment consisting of Central Russia and the Urals, while the southern part of its range includes theCaucasus and Crimea. On the basis of morphological and molecular-genetic data, the taxonomic status of its Caucasianforms is discussed. In the Eastern Caucasus (Republic of Dagestan, Russia), we caught Myotis animals related to thegroup of «Myotis nattereri» species, similar to specimens of the West Asian Myotis cf. tschuliensis on the basis of skullsize measurements. A comparison analysis showed that, outwardly, M. cf. tschuliensis 2 individuals are highly similar tospecimens from Central Russia. However, these animals have some differences in the ear structure, os penis, attachmentof the posterior edge of the wing membrane to the foot, and in the ratio of cilia lengths to bristles on the free edge of thetail membrane. The more reliable differences between M. cf. tschuliensis 2 animals and M. nattereri s.str. specimens wererevealed on the basis of craniometric studies, but the complete confirmation of the species’ independence of Caucasianspecimens was obtained using the analysis of mtDNA sequences. According to phylogenetic constructions, Dagestanspecimens designated by us as M. cf. tschuliensis 2, formed a well separated sister line in relation to the clade of Caucasian forms: M. schaubi and M. cf. tschuliensis 1 (p-distance: 7.4–7.0%). There are no reliable morphological differencesbetween M. cf. tschuliensis 2 and M. cf. tschuliensis 1. Prior to genetic studies of M. tschuliensis specimens, we suggestusing an open nomenclature for the East Caucasian form. If specimens designated as M. cf. tschuliensis 1, originated fromthe Near East, are genetically identical to the M. cf. tschuliensis specimens from its type location in Turkmenistan, thenDagestan bats designated as M. cf. tschuliensis 2 should be considered as a new, undescribed species.
