Promachus
And I will have to pull key to attempt species. But this is a fine male. P. bastardii does not occur in AZ. So this is one I have not seen. It is not minisculus, sackeni or albifacies so will be new for the guide.

By elimination, this must be atrox or magnus and I have no description for either.

Promachus
I now have the P. atrox description and it has a very white mystax. This may be P. magnus, still not 100%.
