Black-tailed Rattlesnake Query

Post by PNWHerper » July 20th, 2014, 1:26 pm

What is the accurate Latin name for the black-tailed rattlesnake found in Sabino Canyon, Tucson, AZ? Is it Crotalus molossus molossus? Or is it Crotalus ornatus?

I am finding some conflicting information on this, and am trying to make sense of it. Anyone have an definitive answers?

Thank you,

Fil

I'm curious as to what information you have that suggests that C. ornatus even comes into Arizona.

Geographically, this basal divergence corre-
sponds to a valley running from southeastern
Otero County, New Mexico through south-
central Presidio County, Texas.
