Arhopalus foveicollis? - Arhopalus

Moved

I will move it to genus Arhopalus for now until there is a confirmation of the species.

Arhopalus at least

I'm sure it's either A. foveicollis or A. rusticus obsoletus. I don't seem to have either to compare it to, though. So, looking at Yanega, there are a few things I see. The elytral ridges in yours don't seem to be quite as pronounced as the A. foveicollis in Yanega, but that could just be the angle and lighting of the photos. Also, the proportions of the antennal in yours (looking mainly at the third segment and the total length) seem to look more like Yanega's A. rusticus obsoletus, but that could be a variation between specimens or sex. I looked hard at the pictures I guess hoping it would pop out like one of those 3D poster things to get an idea about the size of the pronotal depressions, but that's hard to really get a gauge on. The eyes in your picture don't seem to be hairy, though. If that's true, I think I'd say Arhopalus foveicollis. Anyway, that's my attempt at looking like I'm giving an answer without actually commiting to anything.

Confusion!

Yeah, I know how you feel. I sat for about an hour comparing the two, and the only thing that I could come up with is the lack of hairy eyes. Thus leading me to believe that it was A. foveicollis.

I think A. rusticus

I have a foveicollis from Maine and it really doesn't look like your beetle. The elytral ridges and pronotal sculpturing are quite prominent and not likely to go away based on the lighting, camera angle, etc. Also the ranges are different. Foveicolis is basically a northern bug although I guess it could come down the Appalachians. A checklist of Maryland Cerambycidae by Charlie Staines (Maryland Entomologist, Volume 3, Number 1, April 1987) gives no records for foveicollis in Maryland so I bet it would be rare in VA if there at all. Rusticus on the other hand was listed from three Maryland counties.
