A medium-sized lizard with a flattened tail and long thin limbs. Dark tail bands become black ventrally, where they starkly contrast the white background. Body is yellow-tan with two dark side bars extending up from the belly just behind the forelimbs. On males, the bars extend onto the belly where they are surrounded by blue patches. On females, the bars are faint or absent and the belly lacks blue patches. External ear openings and forward position of side bars distinguish it from from the similar Greater Earless Lizard.
