A medium-sized lizard with long legs and a long tail, a somewhat large triangular head, and granular scales. It can grow to a length of 10.8 cm from snout to vent, and is characterized by a distinct collar across its shoulders; typically a thicker black band bordered on each side by thinner white bands. The collar is often broken in the center of the back. The rest of the body is tan with small cream spots, often aligned in rows across the body. Adults develop a yellow tint on their legs and cream markings. In cross-section its tail is round, which distinguishes it from similar species.
