Also, once the leopard gecko grows to be an adult it will be much larger than the central American banded gecko. If you mean breed; no, reptile species should not be mixed.

There are over 60 species of lizards in Arizona. Some common ones include the desert spiny lizard, western banded gecko, and horned lizard.
The Desert Banded Gecko is preyed upon by a variety of predators, including larger reptiles, birds, and small mammals. Common predators include snakes, such as the western rattlesnake, as well as birds of prey like hawks and owls. Additionally, small carnivorous mammals, like foxes and weasels, may also hunt these geckos. Their camouflage and nocturnal habits help them avoid many of these threats.
The lizard you are describing is likely a western whiptail lizard (Aspidoscelis tigris) or a common five-lined skink (Plestiodon fasciatus). Both species are known for their tan coloration with black horizontal stripes.
They have the same name, but their color might be different. The spots and striped might be at their tail, the whole body, or the head. Their skin colors can be yellow, pinkish-orange, and that's all i know. :D
