Badiane et al. (2014) found the taxon Pristurus rupestris to contain two genetically well-differentiated species: an eastern clade (=Pristurus rupestris rupestris) that occurs in coastal Iran and the Hajar Mountain range in northern Oman and the eastern UAE, and a western clade distributed from coastal central Oman, through Yemen, Saudi Arabia and up to southern Jordan, with two possible names available: Pristurus guweirensis Haas, 1943 (=P. r. guweirensis elevated to species) or Pristurus migiurtinicus Scortecci, 1933 (synonymized with P. rupestris by Loveridge (1947). Further comparison of material from the type localities of Pristurus guweirensis and Pristurus migiurtinicus is required to confirm which is the applicable name for the western clade taxon, and Badiane et al. (2014) refer to the western clade as Pristurus sp. 1.The resulting P. rupestris concept includes two nominal subspecies, P. r. rupestris (endemic to the Hajar Mountains) and P. r. iranicus (endemic to coastal Iran). P. r. iranicus is, however, morphologically identical to P. r. rupestris and recognizing it has been found to render P. r. rupestris paraphyletic, and it is possible that work in the near future may synonymize it within P. r. rupestris (S. Carranza pers. comm. 2018).Within the Hajar Mountains, populations are a species complex that requires further study, and the taxonomic identity of subpopulations are likely to change (Garcia-Porta et al. 2017, Carranza et al. 2018).
