Wow... I guess there really are a lot of Whiptails! I didn't really realize. Unfortunately, you are all wrong. Here's a hint... I live in Arizona and I see these guys every time I got up in higher elevations.... and its not an Arizona Striped Whiptail.
The good news is that there's only like 10 or 11 Whiptail species in Arizona and I think you guys have just about covered most of them.
