Anaquedius vernix
Actually, Anaquedius has two distinct punctures on the pronotum (obscured here by moisture), and a prominent inner spur at the protibial apex (barely visible. It is easy to be positive when I have the specimen in hand.

The head and pronotum were shiny, with no punctures.

Hmm, hmm
Quediina subtribe is correct guess, insofar.
The elytra of this beetle seem glabrous and impunctate to me. If so, it can´t be Quedius - otherwise, yes.

Well, in this case, by elimin
Well, in this case, by elimination, in Eastern North-America it can only be the genera Anaquedius or Hemiquedius, and since I don't see any puncture in the middle of the front, I think it is Anaquedius.
