Nerax
This is a Nerax [Efferia] species. And likely N aestuans though it is a bit dark to verify that the tibiaes have some red on them. There are two othr species out in the east but in Virginia this is likely Nerax aestuans.

I'll just move...
...to Nerax, unless there's a better-lit shot to confirm species ID.
