The pronotum...

...is what I was trying to get a better look at. Acmaeops proteus has distinct dorsolateral tubercles, giving the pronotum a wedge-shaped appearance - I don't really see it in this pic or the closeup, but it could be the angle of the light. The body form is right, and especially the uninflated post-ocular region of the head (no distinctly narrowed neck) - I guess by process of elimination I can't really think of anything else it could be.

Gnathacmaeops is a different genus, with G. pratensis being the only Nearctic member. It is similar in form but has a distinctly more elongate "face," along with minute but distinct elytral pubescence. I haven't seen any all black individuals of G. pratensis, although maybe they exist.

Brachysomida bivittata

I think it's a very dark form Brachysomida bivittata?

Yep...

...that's it - good call. I've not seen an all black one, but the type photo page shows a few

A guess....

Just taking a guess, but it looks similar (especially the pronotum) to Acmaeops proteus in Yanega's guide. (Although it seems the genus has changed to Gnathacmaeops ??)

I'm stumped...

...on the species (or even genus) - can you crop and present a larger image of the beetle?

Moved from Longhorned Beetles.

Yes.

This is one of the flower longhorns, subfamily Lepturinae. Nice shot.
