The Sinai agama is an agamid lizard found in arid areas of the United Arab Emirates, southeastern Libya, eastern Egypt, Israel, Jordan, Syria, Saudi Arabia, Oman, eastern Sudan, Ethiopia, Eritrea, and Djibouti.
The Sinai agama is a small lizard with long legs, giving it an upright stance. It grows to a length of 18 cm (7 in) and has a long, slender tail, one and a half times as long as the body. The long head has the eyes fairly near the front with a distinctive pair of ear openings some way behind in line with the animal’s mouth. The legs are long and slender and the tail is often held off the ground.
This lizard is generally a dull brown colour, but during the breeding season, the male turns bright blue, or sometimes just the head and throat turn blue with the other parts remaining brown. Females and juveniles are greyish-brown all year round, but females often have a crescent-shaped red patch on each side just behind the forelimbs.
The scales on the dorsal surface are relatively small, uniformly overlapping, and slightly keeled. The mid-back scales are slightly larger than elsewhere, and the scales on the tail are larger than those on the back. Unlike members of the closely related genus Agama, the third (middle) toe is the longest instead of the fourth.
