Bark-Gnawing Beetle - Tenebroides corticalis

Bark-Gnawing Beetle - Tenebroides corticalis
Near Ruraldale, Upshur County, West Virginia, USA
April 15, 2005
Found under bark. Bark-Gnawing Beetle family, Trogossitidae? If so it is only the second species in this family for the guide. I don't have any experience with this family, so confirmation, correction, or elaboration would be appreciated.

Moved
Moved from Tenebroides laticollis. I think corticalis is a better fit.

Moved tentatively
Moved from Tenebroides.

Tenebroides sp.
Yep, it's a bark-gnawing beetle: Tenebroides sp. (Trogossitidae: Trogossitinae). There are apparently 21 species in North America, and they all look pretty much like this one, so I wouldn't hazard a guess on a species name. Nice to have the representation, though!

cheers,

Zack

 
Thanks, Zack
Thanks, Zack! I had paused by the drawing of T. mauritanicus in my Dillon & Dillon, but then saw that that particular species is a pest of stored grains. Then again, maybe they have a niche in the non-human world too, under bark.

But I am just glad to get confirmation of family from you and Phillip, and the genus is just icing on the cake! Thanks again.

Info
Yes, T. mauritanicus is an introduced flour/grain pest, but many/most(?) of our native species can be found under bark. There are 12 spp. listed from Florida.

Sure
These can be confusing - I've seen these ID'd as Stag Beetles [Lucanidae], which is somewhat understandable - they have prominent mandibles and have antenna that look almost Lucanid like, but you're right.
