Yes, a throscid
There are two eastern U.S. genera: Aulonothroscus and Trixagus, with a total of 19 species. The distinguishing characters are almost all ventral.

Thanks, Michael!
I added a ventral shot. Is it helpful?

Aulonothroscus
has oblique grooves in the metasternum for the mid tarsi. Trixagus does not. I can't really make out the condition of the metasternum in the picture.

Thanks, Michael!
It's still alive and I'll try to get a better ventral image and let you know when prepared.
