Diagnosis

M. davidii is morphologically similar to M. mystacinus , M. ikonnikovi , M. brandtii and M. sibiricus . It differs from other species by the smaller forearm, lower leg; singular third upper premolar is small or absent, when present, it is always lower than the second upper premolar; paraconuli absent ( Dietz and Helversen 2004, Tsytsulina et al. 2012). The base of the hair is dark, the tip is light, the wing membranes and ears are dark Fig. 1

Results

A total of 28 M. davidii individuals were caught: 26 in the Altai-Sayan region and 2 in the Southern Urals (Table 1). All animals were from the terrains located beyond the known limits of distribution of this species.
