Assessment rationale/justification
The species is known form just a few scattered localities with a highly restricted EOO and AOO, although it is not considered to be uncommon within this range and may well be under-recorded due to being overlooked. Declines have been observed around Jebel Hafeet, which are suspected to be continuing. As a result, the species is assessed as Endangered (B1ab(ii,iii,iv,v)+2ab(ii,iii,iv,v)).
