Moved from ID Request.

Looks like Apenes lucidula.

Yes! That appears to be spot
Yes! That appears to be spot on. It is obvious why I was having trouble since I was using Bousquet and this is a more southern species. I wish this specimen was in better shape. It is quite beautiful and I think this is the only one we have after an entire summer of collecting from pitfalls. I was looking at Lindroth and I don't see a habitat description for this species. Is there another resource for this species? Could this possibly be a state record?

I agree, it's a beautiful beetle!
"Ground Beetles and Wrinkled Bark Beetles of South Carolina" by Janet Ciegler, available from Clemson University Press, for about 20 dollars I think, covers many more southern species that aren't in the area covered by Bousquet's identification guide to the NE. There are some that aren't in either book, of course.. It doesn't have much info on habitat, but it's a good second key to have.

"Catalogue of Geadephaga (Coleoptera, Adephaga) of America, north of Mexico" by Yves Bousquet, available online for free, is a huge resource of information on the occurrence of carabids. Peter Messer maintains new records for Carabids here(1).
This species is widespread, and has been recorded from Illinois.

The genus as a whole seems to be poorly-understood, with not much known about its lifestyle. Just glancing in Larochelle and Lariviere's 2003 book on carabid natural history, looks like this species is wing-dimorphic, sometimes attracted to lights, found at a wide range of elevations, and seems to commonly occur in leaf litter.
I've only seen one of these myself, which was on a hiking trail at night. It moved in a bizarre skittery manner, more like a jumping spider than a carabid.

Thanks for the information. I should probably add Ciegler's book to my library.
