Cardiophorus robustus
I have examined the specimen in-hand and do believe this is C. robustus! The habitus is stout, 'robust', very hairy with wirey vesiture; submarginal line on hypomeron not reaching lateral margin; prosternal process margined ventrally to apex.

Thanks for the contribution to BG and a new species for my reference collection!

Thanks, and congratulations Brandon and Blaine!
This find makes me so happy! I had been concerned about this species since about 2000. It had apparently been nearly 50 years since anyone had collected one. I was even a little worried that it might be extinct, since it seems endemic to a small and much urbanized region. I had been meaning to go to Massachusetts to search for robustus myself. Hume

I'll try to get a photo of the prosternal process later today.

cardiophorine... intriguing

my thoughts too...
I am thinking Cardiophorus, but something about the angle or maybe just imaging artifacts that does not look right. The scutellum seems deeply incised anteriorly, supporting Cardiophorus, and they are often found on beaches and other sandy areas. If this is Cardiophorus, I am thinking C. convexus. Doesn't look right for C. gagates and the pronotal setae near the hind angles look too long for C. erythropus. I'm not familar enought with C. convexulus to rule it out. I'll bounce it by Hume Douglas.

from Hume Douglas:
"This female might be Cardiophorus convexulus (LeConte), a new species for bugguide. The only other possibility is Cardiophorus robustus LeConte, which has not been collected since 1965 to my knowledge. These are the only two species with such heavy-duty ovipositor coxite in the east. If the prosternal process is margined laterally, it's robustus, which would be exciting and a relief. The reason that I'm a little optimistic that it might be robustus is that it looks kind of hairy. I'm pretty sure that the search for this species has been less exhaustive though."
