Beetle, Odd Body - Phenolia grossa

Beetle, Odd Body - Phenolia grossa
Albemarle County, Virginia, USA
Photographed on June 5 a number of years ago. Found under bark. I love the body shape of this beetle, with the sides of the pronotum and elytra flattened. The body shape makes me think of the Nitidulidae, but then again Chrysomelids can have this kind of tortoise-like shape too. Any help with ID appreciated.

Hi Stephen,
One of the nitidulid specialists I contacted to look at the unidentifieds in this family passed the request along to Andrew Cline, an insect systematist for the State of California. Here is his CV of 10 months ago. Presumably his PhD has been awarded by now.

At any rate, he conducted a whirlwind tour through our Nitidulidae, dropping IDs as he went. Neat!

Phenolia grossa (Fabricius 1801) ?
Stephen-

I can't be absolutely sure, but this looks most like a specimen of Phenolia grossa, a widespread species (the only one in the genus) in the Eastern US. There are a number of nitidulid genera that have this general appearance, and I'd have to actually key it out to be sure.

cheers,

zack

Sap beetle
Good instincts, Stephen, it IS a nitidulid, possibly Cryptarcha sp., emphasis on "possibly":-)
