| Abstract: | Recent study on Lasiopodomys (Stenocranius) gregalis has revealed four clear mitochondrial lineages with differences exceeding the species level. The most divergent is the clade from south‐eastern Transbaikalia. Multilocus (six nuclear genes), morphological (dental characters of m1 and M3) and behavioural (breeding experiments) analyses were conducted to test the hypothesis that L. gregalis is a complex of two cryptic species. All of the applied methods distinguish the independent status of voles from south‐eastern Transbaikalia. This clade occupies a portion of the distribution range of the currently valid subspecies L. g. raddei including its terra typica. According to the results of cyt b analysis, the lectotype of L. g. raddei belongs to the Transbaikal clade. We re‐establish the species status for the taxon Lasiopodomys raddei including populations from south‐eastern Transbaikalia, as a cryptic species of the narrow‐headed vole complex. |
