Ashkhabad Dwarf Racer

E. medus can be distinguished from other Eirenis species by its dorsal scale count of 15 smooth rows and its 50 narrow crossbars along its dorsum. They may get as long as 430 mm long with males having a greater range of length being both the smallest and largest specimens, although females are larger than males on average. E. medus has a light greyish-brown dorsal surface with brown crossbars and a salmon belly. It is oviparous and delivers clutches of 2–3 eggs which can get up to 18 mm long.

E. medus is considered to be a nocturnal species. It exhibits limited diurnal activity, however. Most of the species' time is spent under stones, which act as both home and hunting grounds. The reasons it may emerge from under its rock are to find new shelters with optimal temperature, humidity, and food, or to find partners during the breeding season. It has been found active on rocky slopes from April through October, though never in midsummer. The population density of E. medus is up to 133 per hectare. The species is considered to be of least concern by the IUCN.
