Аннотация: A phylogeographic study of the Northern Three-toed Jerboa, Dipus sagitta, which has one of the largest geographic ranges among Palearctic desert rodents, was performed using complete mitochondrial cytochrome b and fragments of two nuclear genes. The phylogenetic analysis of the cytb data including 222 specimens from 69 localities revealed six allopatric lineages divergent at 7.4–10.1%. At least some of them are supported by nuclear data, thus, confirming high level of cryptic diversity within D. sagitta. The recovered pattern of genetic differentiation was reviewed from a taxonomic perspective. In general, mitochondrial lineages show relatively good correlation with morphogical subspecies. Both mitochondrial and nuclear data support the isolated position of the Qaidam lineage, which diverged from the rest in the Early Pleistocene (~1.5 Myr) according to our molecular clock results. Therefore, we propose to recognize it as a separate species Dipus deasyi; the taxonomic status of other lineages remains to be clarified. The results are consistent with the hypothesis that the center of the origin of D. sagitta complex is located in the eastern part of the range. The geographic structure of genetic variation in D. sagitta is compared to those in other desert rodents.
