The Sinai agama (Pseudotrapelus sinaitus, formerly Agama sinaita) is an agamid lizard found in arid areas of southeastern Libya, eastern Egypt, Israel, Jordan, Syria, Saudi Arabia, the United Arab Emirates, Oman, eastern Sudan, Ethiopia, Eritrea, and Djibouti.
The length of the lizard including its long slender tail is 18 cm (7 in), the tail accounting for up to two-thirds of its total length. The limbs and tail are long and thin and allow for good climbing and running capability.
Pseudotrapelus sinaitus is active during daytime and feeds on insects and other arthropods and plants. During the breeding season, males become a striking blue colour to attract females. The female has brownish-red spots on her sides.
