They have a dark background coloration, with four white stripes running lengthwise across their body, to which they owe their name. The limbs may be speckled with white, and the belly is white or pinkish. They are robust lizards, with strong limbs and a long tail (about twice as long as the distance between the snout and the cloaca). Males are usually larger and more robust than females and have more distinct pores on the hind limbs than females. The ventral scales are overlapping one another.
