Assessment rationale/justification
This species is apparently known from two records in the UAE, from urban areas close to Dubai, however, its distribution is obscured by confusion with other members of the genus. Whilst the species may be native to the UAE, it has to be suspected that it occurs as the result of introduction. Further research is required for this species to confirm its origin, current distribution, population size and population trend; it is currently considered as Data Deficient.
