Pseudotrapelus sinaitus (Heyden, 1827).

Length up to 90 mm. A slender agamid lizard with a large triangular-head from the ventral aspect. The external ear opening is larger than the eye; the dorsal scales are relatively small and uniform, pointed, keeled, and imbricated; limbs are very long. The color varies according to the physiological state and sex; non-breeding individuals from both sexes are grey. The breeding male has a bright cobalt blue head and chest, while the female is grey with transverse orange bars. The Sinai Agama inhabits rocky wadis in arid deserts, where it can typically be seen on large boulders. It is strictly diurnal; its diet consists of insects including ants. Five to nine eggs are laid; the egg number and size increase with the female’s length. In Egypt, it is found in the Eastern Desert and Sinai, and its global range extends from North Africa to Arabia. It is widespread and common.
