If I had known that this was a seldom-encountered ant, I would have taken other views before removing his wing. Hopefully there will be a next time so I can offer other angles.

There are four species of Acanthostichus in the state of Arizona, all distributed mostly in the southern half of the state. The similar Syscia augustae is also found in the area. Finding males would require combing blacklight sheets for tiny waspy things for a long time, but for workers you would have to flip a bunch of rocks/termite food(dried cow dung) and have an incredible amount of luck, as they don't ever come aboveground.

It is a good thing that you took the wing off for better shots, the wing venation of ants is often not too well known and there are not that many good pictures online of them.
