Taxon distribution as listed in assessment
Within the United Arab Emirates, this species is found throughout the sandy deserts from Ras al Khaimah to western Abu Dhabi, including the Liwa area (Gardner 2013, Burriel-Carranza et al. in press). Occurs from sea level to 300 m asl. Globally, this species ranges from western Iran (a limited small dune area), southern Iraq and Kuwait, into the Arabian Peninsula where it is found in northern and central Saudi Arabia, Oman and the United Arab Emirates (Sindaco and Jerem√§¬ćenko 2008). It is found from sea level to around 1,000 m asl.

Habitat details as listed in assessment
This species is found on sand sheets and dunes including the upper shoreline of sandy beaches (Gardner 2013).It is a nocturnal and fossorial species that spends most of its life under the sand. At night, they may surface and move considerable distances whilst foraging (Gardner 2013). They are predators which are presumed to consume arthropods and perhaps small geckos (Gardner 2013). They are able to tolerate a wide range of temperature while maintaining a mean selected body temperature within a narrow range (Gardner 2013). Very little is known about the species reproduction, although it may be similar to the observation made in Saudi Arabia, where the breeding season was recorded from early April to late June (Al-Sadoon et al. 2014). Females lay 6-9 eggs with an average egg diameter of 1.5 mm (Al-Sadoon et al. 2014).

Least Concern
Assessment status abreviation
Assessment rationale/justification
Within the United Arab Emirates, this species is found throughout the sandy deserts from Ras al Khaimah to western Abu Dhabi. It is listed as Least Concern in view of its wide distribution, presumed large population with no major threats and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. This taxon is not a non-breeding visitor, and it is presumed that any immigration from populations outside the UAE is not significant, and therefore there is no adjustment to the Category according to the IUCN regional and national Guidelines (IUCN 2012).
