Taxon distribution as listed in assessment
Within the United Arab Emirates, the species is known from a single locality, the Wadi Al Helo area from 300-400 m asl (Burriel-Carranza et al. in press). No further records are known in the UAE, but further survey is required.This newly-described species is endemic to the northern Hajar Mountains in Oman and the United Arab Emirates (Carranza et al. 2016). It has only been found in a very few high altitude localities (1,315-“1,434 m asl) in the Musandam Peninsula, Oman (surrounded by A. gardneri at lower elevations) and in two other localities 75 and 120 km further south in Oman and the UAE, respectively, both at relatively low elevations (122 and 374 m asl) (Carranza et al. 2016).

Habitat details as listed in assessment
Strictly nocturnal, this species has been found on the rocky sides of wadis, stony substrates and on larger boulders in the wadi (Carranza et al. 2016). The species breeds throughout the year, with a peak during spring (J. Els pers. comm. 2018). Females lay a single round, hard-shelled egg multiple times during the year (J. Els pers. comm. 2018).

Assessment rationale/justification
Within the United Arab Emirates, the species is currently only known from the Wadi Al Helo area. The species is listed as Vulnerable (VU D2) due to its small area of occupancy (AOO) and extent of occurrence (EOO) of 4 km<sup>2</sup>. 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). Despite occurring at low densities, the population appears stable at present. There are potential threats from infrastructure development, that could significantly impact the population size of the species.The species is new to science with the possibility that more populations may be discovered in similar habitat in the future. The species should be reassessed if new data become available.
