Tenebrionidae? Tenebrionidae?

Moved from Beetles.

Cryptophagidae, I believe
Hi Kristi,
I would guess Cryptophagidae (and next best guess Mycetophagidae). Tenebrionids have a distinct frontal ridge where the antenna come out beneath and the antenna are not clubbed.

Do you know the tarsi formula?

I actually have this same beetle in my reference collection! They are a fungus-eating beetle, I believe.

Sorry for the long delay in saying thank you! I am still new to entomology, with more of an ecologist slant than taxonomy, hence my call for help with identifications :-)
