It is endemic to the lower Jordan Valley along the Dead Sea, in Israel and Jordan, and in the Syrian desert, Central Iraq and in the coastal regions of Saudi Arabia, the islands of Bahrain, Qatar, and Iran, commonly known in Arabic by the names ʾušnān and šenān and in the Neo-Aramaic languages by reflexes of ʾuḥlā.
