The Mongolian racerunner, Eremias argus, is a small lizard endemic to Northeast Asia that can serve as an excellent model for investigating how geography and past climate change have jointly influenced the evolution of biodiversity in this region. To elucidate the processes underlying its diversification and demography, we reconstructed the range-wide phylogeographic pattern and evolutionary trajectory, using phylogenetic, population genetic, landscape genetic, Bayesian phylogeographic reconstruction and ecological niche modeling approaches. Phylogenetic analyses of the mtDNA cyt b gene revealed eight lineages that were unbounded by geographic region. The genetic structure of E. argus was mainly determined by geographic distance. Divergence dating indicated that E. argus and E. brenchleyi diverged during the Mid-Pliocene Warm Period. E. argus was estimated to have coalesced at~0.4351 Ma (Marine Isotope Stage 19). Bayesian phylogeographic diffusion analysis revealed out-of-Inner Mongolia and rapid colonization events from the end of the Last Interglacial to the Last Glacial Maximum, which is consistent with the expanded suitable range of the Last Glacial Maximum. Pre-Last Glacial Maximum growth of population is presented for most lineages of E. argus. The Glacial Maximum contraction model and the previous multiple glacial refugia hypotheses are rejected. This may be due to an increase in the amount of climatically favorable habitats in Northeast Asia. Furthermore, E. argus barbouri most likely represents an invalid taxon. The present study is the first to report a range-wide phylogeography of reptiles over such a large region in Northeast Asia. Our results make a significant contribution towards understanding the biogeography of the entire Northeast Asia.

Eremias Fitzinger, 1834 is a speciose Eurasian genus of true lizards with approximately 40 species. Eremias species occurring in Pakistan have never been examined before using molecular genetics. In the present study, six out of seven morphologically defined taxa distributed in Pakistan (E. acutirostris, E. aporosceles, E. cholistanica, E. kakari, E. persica, and E. scripta) were studied using mitochondrial (16S rRNA, cytochrome c oxidase subunit I, cytochrome b) and nuclear (Rag1) genes. Data of 29 individuals were included in phylogenies using ENA/GenBank sequences. With a maximum of 20 species per analyzed data set, this study represents the most complete phylogeny of the genus to date. Maximum Likelihood and Bayesian analyses were run for concatenated (3,528 bp) and single‐locus data sets and supported by uncorrected p distance calculations to evaluate the phylogenetic placement and divergence of Pakistani taxa. Among the Pakistani taxa, we detected six mostly well‐supported and deeply divergent clades (A‐F) differing by uncorrected p distances of up to 23.8% for mtDNA (cytb) and 3.3% for the nuclear Rag1 locus. Despite morphological differences between E. aporosceles and E. acutirostris (both clade A), no unambiguous genetic support was found for these two taxa. Therefore, we regard E. aporosceles as a synonym of E. acutirostris. On the other hand, E. persica was found to represent a species complex with deeply diverged clades (E and F) in Pakistan. Eremias cholistanica (clade D) and E. kakari (clade B), two morphologically defined endemic taxa of Pakistan, were revealed as phylogenetically clearly distinct. Eremias scripta (clade C) from Pakistan was found to be genetically deeply divergent compared to sequences of this taxon from Afghanistan and Uzbekistan. Our study provides evidence that the current taxonomy of Eremias does neither reflect the genetic diversity nor the evolutionary history of the genus, necessitating a comprehensive integrative taxonomic revision of the whole genus.
