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.

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.
