Dahl’s jird, Meriones dahli, is a critically endangered species restricted to a small area in central Transcaucasia. The phylogenetic position of Dahl’s jird within the Midday jird species complex was assessed based on the DNA of museum material. Both mitochondrial and nuclear gene sequences were employed. Dahl’s jird has been found to be a sister group close to M. penicilliger, which is distributed in Turan. This result suggests the existence of a late Middle Pleistocene dispersal corridor for psammophilic species that is known to have connected the Transcaucasian and Transcaspian regions.
