Please note, this National Red List website contains a subset of data whilst we transition to national focal point driven data uploads. We thank you for your patience with this and welcome national contributors to get in touch to update their national dataset. Terms of Use including citation guidance are found here.

The previous dataset is available via: https://archive.nationalredlist.org/. This site is no longer updated but can help with most enquiries whilst we focus on redevelopment.

Assessment rationale/justification
Although this species is fairly restricted within the UAE, and was generally considered to be rare in the country, it has been discovered to be locally common within the Wadi Wurayah National Park. This suggests that it may occur in other locations of the Hajar Mountains were it could have been previously overlooked. It is assessed as Least Concern.
