Calyptratae fly
Muscidae or Anthomyiidae. It's deformed, because somehow after coming out of the pupa it didn't manage to unfold it's wings and they dried like this. It will not survive very long like this, easy target for all kinds of predators.
It happens more often with these critters.

....
Other than the fly in hand, what would you need to at least get it to genus?

Also, is Calyptratae a family level (BugGuide just has it as "no taxon"), or what is it exactly?

Ok, thanks.
And what about the first question regarding genus?

Hmmm
You can forget about that, one would need it's wing venation, for instance. Or the tip of the scutellum, to see whether there are very fine hairs on the underside or not.
That's sometimes even hard with a pinned specimen at hand!
From this picture one can't even tell the family for sure.
greetings
