Wasmannia auropunctata, an invasive tramp species.
In Virginia?
There doesn't seem to be any particular distribution pattern in the US. I imagine it exists inconspicuously in lots of areas. She's not any of the documented myrmicine genera.
I agree, it just doesn't feel right. If @Yubyop is finding mated alates of W. auropunctata outside of Richmond, it means that there's a colony that's not only established, but thriving, and unless it's held up in his house or some other structure to escape the cold, I just don't see this species being able to make it there.
@Yubyop, you mentioned you couldn't get better pictures, but maybe you have some way of getting a closer look, like with a loupe or other magnifying glass?
For W. auropunctata, look for the following combination of characteristics:
1. Antennae are 11 segmented, with the last two (not three) forming a distinct club. There is an obvious club in your pictures, but it's too blurry to tell if the club is two or three segmented.
2. There are prominent (and I mean prominent) frontal carinae extending the length of the head.
3. The petiole from the side view is distinctly square.
4. There are propodeal spines present. (And while you're looking over it, are there obvious ocelli? Those should also be present.)
If you have this combination of characteristics, W. auropunctata is what you have, which, again, I'd find surprising for that climate.
You should also take a look at the queen pictures on the AntWiki page for that species to familiarize yourself with the morphology you should be seeing.
