This looks to me like a common Deerfly. Is it in fact?

Bombyliidae
Nope, not a deerfly, it is a beefly and uses the long proboscis for sucking up nectar and not blood...
Very nice fly!
Great shot

Are you sure this is a beefly?
It looks an awful lot like a stiletto fly.

Edit: I do see some definite differences, in the eyes and the amount of hair on the fly's underside and legs... and in the relative sizes of the various parts (long proboscis, long legs, short abdomen). So never mind. :)

Thanks, Martin...
I've edited the title accordingly.

Now, maybe someone can narrow it to genus?

Poecilognathus
I asked Neal Evenhuis and he he said:
"It's a species of Poecilognathus, but until I see the male gonies, hard to tell what species -- Arizona has about 5 new species in the thlypsomyzoides group (spotted wings). If you need a name on it, you can say scolopax, since tht species is widespread and it will probably key to it."
