Assessment rationale/justification
Although this species is known to occur within the Hajar Mountains, detailed information regarding its population size and trend is lacking. It is not considered to be a common species, although it may be under-recorded due to its resemblance to the much more common E. hispanica (G.R. Feulner pers. comm. 2020). It is not known whether it occurs in any protected areas, nor if it is subject to any threats. As a result, it is assessed as Data Deficient.
