This lizard's range is mostly in Mexico, but intersects a tiny little bit of southeastern Arizona and southwestern New Mexico. We saw just one of these tykes in the Chiricahua National Monument, which was littered with Mountain Spiny Lizards, another species in the same genus. Every time we saw another lizard it turned out to be another Mountain Spiny. When my friend John McCaffrey found this individual, he was very excited to realize that it was at long last a different species.
