Moved from Corticaria.


Image is updated
taken through a steroscope. Hope it helps...

Keys to Corticaria
from American Beetles but it's definitely not parallela, which is the only one listed for Alberta and shown in MCZ. The colour seems to be distinctive though...
Edit: Looks like C. varicolor pictured here though it is listed only for BC.

Thanks for the new photo Tim. It certainly is Corticaria.
Our knowledge of the North American Corticariines is very poor, and as such, the checklist doesn't help much, but people like you can help to fill the gaps :-)

Using the color and size of your specimen, it may fit Corticaria varicolor or C. impressa. If the elytra surface is sparsely wrinkled between punctures and the hairs are conspicuous (as in the type) then it's varicolor. If the basal fovea of your specimen is more distinct, lateral crenulations of the pronotum indistinct, and the hairs seem to be shorter and less conspicuous, it may be impressa (Majka et al 2009).

Thanks for confirming :)
will reexamine the specimen later today...

Appears to be C. varicolor
after re-scoping it...

Moved from Corticariinae.

I've looked at these 2 a number of times because they don't strike me as Latridiids, yet I'm not sure which family they belong to. Perhaps moving them broader will bring the attention of other beetle fanatics :-)

caught mine
a desperate guess: Myrmechixenus??

if so, can be fun: seems to have wide head & small eyes [can't make a conclusive opinion from the pic]
