Assessment rationale/justification
Within the United Arab Emirates, this species is found in the carbonate mountains of the Ru'us al-Jibal in the Western Hajars north of the Masafi/ Dibba depression. The species is listed as Least Concern as there are no threats to the species within its restricted area of occupancy (AOO) of 20 km<sup>2</sup> and extent of occurrence (EOO) 263 km<sup>2</sup>, and in view of its presumed stable population that is unlikely to be declining fast enough to qualify for listing in a 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).However, the species occurs with a very restricted AOO and EOO, and at very low population densities. Ongoing monitoring is needed for this species, and it should be reassessed if new data become available.

Habitat details as listed in assessment
Cliffs, cave fissures, rocks and boulders within mountainous habitats at different heights (Simó-Riudalbas et al. 2017). It is a nocturnal species that may also be encountered in the shade during the day on rock surfaces (Simó-Riudalbas et al. 2017). Reproduction is presumed to be similar to Ptyodactylus orlovi, with females laying one to two eggs during summer.
