Taxonomic Notes
Mendes et al. (2018) undertook a genetic study across the Hajar Mountains and found this species to comprise of two very distinct genetic lineages that may correspond to two independent species.
Taxon distribution as listed in assessment
Within the United Arab Emirates, this species occurs throughout the Hajar Mountains from 200 m to 700 m asl (Gardner 2013, Mendes et al. 2018, Burriel-Carranza et al. in press).Globally, the species is endemic to the Hajar Mountains of northern Oman and the United Arab Emirates (Sindaco and Jeremäenko 2008, Gardner 2013, Mendes et al. 2018).

Habitat
Habitat details as listed in assessment
The species is found on bedrock wadi banks and coarse gravel wadi beds, particularly near areas with permanent or intermittent surface water pools from 200 m to 700 m asl. The species has also been recorded from plantations in the Hajar Mountains. It is a small and elusive diurnal species, which upon detection of a potential threat will rapidly retreat into rock cracks and crevices. Combined with its small size, long flight distance and the rocky habitat it occupies, the species is often under-sampled during surveys. It is active throughout the year, although during the summer months, activity is limited to the early mornings and late afternoons. They appear to be predominantly solitary, with pairing observed during the cooler months from October to May. Females lay several clutches of two to three large eggs measuring 9 by 4 mm (Gardner 2013). Hatchling measured 25 mm snout to tail length with a tail length of 55 mm (Gardner 2013).

Assessment rationale/justification
Within the United Arab Emirates, this species occurs throughout the Hajar Mountains. The species is listed as Least Concern as there are no significant threats within the majority of its area of occupancy (100 km<sup>2</sup>) 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).

Conservation
Threats listed in assessment
The species is threatened by quarrying for rocks in some parts of its range. Populations surrounding permanent or seasonal water bodies may be subject to disturbance from recreational activities, although this will influence a small percentage of the total population.
