A. chalcodes??

Caught this one around Phoenix, AZ. This pic is one day post molt and the colors are a lot more drastic than before molt. Can anyone confirm if it's A chalcodes?
Yes, there are small color variations among individuals as well as changes in appearance over time after molting. Morphologically, they're identical.
 
North America has a vast area of landmass that is habitable to the few species of tarantula we have. The vastness of the habitable land mass accounts for a large variety of climates, which thanks to micro evolution "adaptation" we see variations in the same sp. from different regions.
 
A. hentzi - "North American Brown", "Oklahoma Brown", "Missouri Brown", 'Texas Brown", "Arizona Brown" all the same sp. and the list goes on.
 
@MrSmith86 I love your answer. When you think about species from other parts of the world, the area that they come from is often very small and wouldn't require the same extent of adaptations due to widely differing climates and living conditions.
Even one state that A. chalcodes comes from, and there are more than one, is bigger than entire countries where other tarantula species are found.
I'm sure that there are many more adaptations, within the Aphonopelma genus, in the U.S., that haven't even been seen yet and maybe never will. You could spend your entire life studying the species in the southern U.S. alone.
 
@ I'll give you mine if i can move to Canada, I hate the USA. Not that im a huge fan of Justin Trudeau or anything.
 
@MrSmith86 Apparently there is a website that has become very popular for people in the U.S. looking to marry Canadians. Plus, our immigration lawyers have been very popular lately. All joking aside... there are a lot of U.S. citizens wanting to move north and citing Donald Trump as the reason.
 
@VanessaS Donald trump is just a distraction, we do this every election we have a few dozen candidates and the news monster only focuses on two terrible choices the candidate that that want to win, and a buffoon.
