). Body is light brown with faint light speckles scattered randomly on the body dorsum. Head is slightly darker than body and has a blue tint in females. The nape is dark. There are prominent dark brown transverse bars across the body, the first is behind the insertion of forelimbs and runs to about the middle of the flank. Another, shorter and less conspicuous dark band is situated before the hind limbs. In some specimens, another small transverse stripe is in the middle of the body, sometimes marked only as a small darker patch. The dark dorsal stripes are orange or have reddish outlines in females. All body parts are white from the ventral side except for the throat, which has a dark background with regular, white, and evenly spaced ocelli. In some specimens, the throat pattern is less discernible and the dark and light scales form a reticulated pattern.

). Most records come from the Tuwaiq Escarpment that runs from southwestern Arabia northeastwards to Riyadh where it bends to the northwest. The escarpment is bordered by massive sand seas: Rub al Khali from the southeast, Ad Dahna from the east, and An Nafud from the north, which seem to form a barrier to dispersal for these rock-dwelling agamas. There are several records west of Tuwaiq, suggesting that the
