Oxytelinae
but not Bledius. I suspect it might be a Carpe*limus, but I´m not familiar enough with the set of genera around it.

Thank you both
keying from Am Beetles Oxytelinae, appears to be unusually straightforward:
6, not 7, visible sternum, with single broad paratergite per side, not two narrow ones = Deleasterini, with only 3 genera.

smaller, 1.5-3mm = not Deleaster
elytra from scutellum at least as long as pronotum, and not from southeastern Canada = Syntomium, not Mitosynum

From Downie and Arnett, only one species from the northeast; S. confragosum Maklin 1854. Description seems to match, but wish I had an image to confirm. Any comments / concerns?

sternites?
or, perhaps I am miscounting the sternites, and there really are 7? Is the first visible one #1 or #2 on roves? If it's 7, then the key is much longer and more difficult.

I see 7 sternites on this rov
I see 7 sternites on this rove, so it's not a member of De*leasterini.

Cheers,

Looks like an Oxyteline to me
Looks like an Oxyteline to me, hard to tell just what one. Initially I thought Bled*ius but not sure if the pronotum is convex enough.
