FIGURE 1. The major deserts of Asia and intervening mountain belts. Major deserts are labeled 1–7 which are: (1) Arabian, (2) Thar, (3) Southwest Asian, (4) Caspian Basin, (5) Gobi-Taklimakan, (6) Qaidam-Qinghai, and (7) High Elevation Tibetan. Intervening mountain belts are labeled A–J which are: (A) Zagroz, (B) Kopet-Dagh, (C) Hindu Kush, (D) Karakorum, (E) Himalaya, (F) Pamir, (G) Tien Shan, (H) Arjin-Qilan, (I) Kunlun, and (J) Tangula Shan. Phrynocephalus species occur in all major desert regions of Asia, with the exception of the Thar Desert in India having Bufoniceps laungwalaensis, which was originally described as a Phrynocephalus species (Sharma 1978) and is the sister taxon to Trapelus (Macey et al. 2006).
