A medium-sized garter snake from northwestern Mexico, the Mexican Wandering Garter Snake, Thamnophis errans, resembles the Western Terrestrial Garter Snake, T. elegans, of which it was at one point considered a subspecies. It’s a relatively drab, brown-gray snake with pale stripes; there may be a pattern of black spots between the stripes. While it resembles T. elegans, T. errans may be more closely related to the Godman’s Garter Snake complex. It has relatively small litters.
