Eremias persica
The Aralo-Caspian racerunner (Eremias persica) is a lizard species found across Iran, southern Turkmenistan, Afghanistan, and western Pakistan. It is characterized by continuous dorsolateral black stripes, which contrast strongly with its base pattern, and juveniles display four dark stripes on their backs. This species inhabits open plains and slopes with low vegetation and gravel surfaces.

About Eremias persica
Eremias persica: The Persian Racerunner
The Eremias persica, commonly known as the Persian racerunner or Aralo-Caspian racerunner, is a species of lacertid lizard native to a broad geographical area encompassing Iranian Azerbaijan, much of Iran, southern Turkmenistan, Afghanistan, and western Pakistan. Described by William Thomas Blanford in 1875, its specific epithet, "persica," directly references its distribution within Persia, the historical name for Iran.
Morphology and Distinctions
This species is closely related to Eremias velox, with which it was previously classified as a subspecies. Both share widespread distribution across the Iranian Plateau and similar scale characteristics. However, Eremias persica can be morphologically distinguished from E. velox by several key features. It exhibits continuous dorsolateral black stripes that stand in strong contrast to its base pattern, unlike the interrupted stripes of E. velox. Furthermore, juveniles of Eremias persica display four dark stripes on their backs situated between dorsolateral white-spotted stripes, and their ventral tail surface is not red, whereas E. velox juveniles have three dark stripes and a carmine red ventral tail surface. Distinguishing juveniles from other species is generally easier than distinguishing adults.
Distribution and Habitat
The Persian racerunner is found across Iran, southern Azerbaijan, southern Turkmenistan, Afghanistan, and western Pakistan. Within Iran, its distribution is extensive across the central plateau, south of the Alborz Mountains, and extends into the Zagros Mountains. It notably avoids the central desert regions of Dasht-e Lut and Dasht-e Kavir. The preferred habitat of Eremias persica consists of open plains and slopes, typically characterized by low vegetation and gravel surfaces. It also occupies areas with a mix of sand, silt, and gravel.
Conservation Status
In 2016, Eremias persica was assessed for the IUCN Red List and categorized as a species of Least Concern. This designation reflects its wide distribution, presumed large population size, and the absence of significant, immediate threats to its survival. A synonym, Eremias nigrolateralis, also shared this 'Least Concern' status due to similar factors, being considered unlikely to be declining at a rate that would warrant a more threatened classification.
