Henoticus? - Henotiderus lorna
HJ Andrews Experimental Forest, Lane County, Oregon, USA
July 1, 2013
Size: 2mm
Found in a in a forest-floor flight-interception trap sample. A few distinctive features may not be obvious in the photos. This beetle has complete, finely denticulate lateral pronotal carinae. In addition, there are complete discal carinae near the sides on the pronotum. The tarsal formula is 5-5-4 --see
(diff. specimen)
Possibly a Henoticus or another Cryptophagid...

Thanks for that. The specimen images at the BOLD website look like a perfect match!

Moved from Beetles.

cool thing, an expert must see specimen
the pronotum with those submarginal carinae reminds me of Mycetaea, but the gestalt is off, and the tarsal formula seems to rule out both the endomychid and biphyllid connections

unfortunately, the image quality is not good enough to show around to people who don't have BG editor accounts, and that's a big, big problem...

 
.
Any way to take another look at the tarsal formula?

 
double-checked
The tarsal formula is 5-5-4.

 
see photo of tarsi for my other specimen
I wasn't able to position the tarsi of this specimen well enough to get a good photo, but I got a reasonable photo of the tarsi of my other specimen. Photos of the other specimen are under the title "Henoticus?-2". Hope that helps.

 
i added the thumbnail to the remarks

 
I agree
I would hazard to say Cryptophagidae.
