Anaxyrus woodhousii Woodhouse's Toad
The genus Anaxyrus was split from Bufo by Frost et al in 2006. This split is particularly controversial among herpetologists, and many references still use the long-established Bufo.
Subspecies I've seen:

My wife and I encountered several of these toads near the San Pedro river. They were all young toadlets, only an inch or so long. I'm not confident that I've identified them correctly; a friend believes that they are probably Red-spotted Toads (Anaxyrus punctatus), but they really don't look like that species to me. At least one other correspondent also thinks they look like red-spotted toads, but to me the head looks too thick and the parotid glands look too large for these to be A. punctatus. If you have any further information, please send me email.
