Came to U/V lights at night. Believe this a Brachinus - Bombardier Beetle of sorts? Confirmation/correction, and further placement would be appreciated.

Moved from Beetles.

B. elongatulus?
It's dangerous to try to ID a Brachinus from pictures, but I ran this through Erwin's key as best I could and got to elongatulus.
In April of this year, I collected dozens of Brachinus in Madera Canyon, and I'm still trying to key them all out. One species I did get a few of was elongatulus, as best I can tell.
I'd recommend keying this yourself since you have the specimen!

 
I concur..
After looking in the keys myself, and basing it mostly by the thorax, I would concur. So I'm going to move this specimen tentatively to elongatulus on this basis. Thank you so much for your help...
