Aspidoscelis costatus Western Mexico Whiptail
The etymology of the genus name “Aspidoscelis” was recently reevaluated and switched from feminine to masculine. Which is kind of ironic with all of the all-female (parthenogenetic) species in this genus. But in any case, this species is referred to in many places as Aspidoscelis costata, the older feminine name.
Subspecies I've seen:
A. c. griseocephalus
Blue-throated Whiptail
Aspidoscelis costatus griseocephalus Blue-throated Whiptail
Rancho Acosta, Álamos, Sonora, MexicoAugust 24, 2017
Blue-throated Whiptail (Aspidoscelis costatus griseocephalus)
I saw a bunch of these whiptails in the area, but only found one that would hold a position long enough for a photo.
