Eremias persica, the Aralo-Caspian racerunner or Persian racerunner, is a species of lizard native to Iranian Azerbaijan, most of Iran, southern Turkmenistan, Afghanistan, and western Pakistan. "Eremias intermedia" is also known as the Aralo-Caspian racerunner.
Taxonomy and conservation.
It was described by William Thomas Blanford in 1875. The type locality is near Isfahan, Iran. The specific epithet "persica" refers to its distribution in Persia (now known as Iran).
"Eremias persica" was assessed for the IUCN Red List in 2016 and considered a species of least concern.
"Eremias nigrolateralis" , the black-sided racerunner, was described based on dorsal color patterning differences but is now considered a synonym of "E. persica". "E. nigrolateralis" was considered a species of least concern on the IUCN Red List based on its extensive, suitable habitat, large population, and presumed lack of significant threats. It was considered "unlikely to be declining fast enough to qualify for listing in a more threatened category". 
Description.
It is most closely related to "Eremias velox", of which it was previously treated as a subspecies, and they share several attributes such as having a wide range distribution across the Iranian Plateau, as well as the number of and shape of their scales. It can be morphologically distinguished from "E. velox" based on several characteristics, including:
Like many other lacertid lizards, the juveniles are more easily distinguished from other species than the adults. Other closely related species of "Eremias" racerunners include  "E. kopetdaghica", "E. isfahanica", "E. lalezharica", "E. montana", "E. papenfussi", "E. strauchi", and "E. suphani".
Distribution and habitat.
The Persian racerunner occurs in Iran, southern Azerbaijan, southern Turkmenistan, Afghanistan, and western Pakistan. In Iran, "Eremias persica" has a broad distribution in the central plateau south of the Alborz Mountains, including the Zagros Mountains, but it is absent from the central deserts Dasht-e Lut and Dasht-e Kavir. It is found in open plains and slopes, typically in areas of low vegetation and gravel surfaces. It is also found on mixed sand or silt and gravel.
