Anyone know the family for this? I'm trying to sort out some beetles in my "family unknown" category. This is one of the smallest beetles I've photographed. I found it walking across my computer desk, at which I unfortunately spend way too much time.

to species page.

The hefty side-mounted antennal insertions a the general habitus resemble Latridiidae, the minute brown scavenger beetles:

It really is exciting to see so many latridiids showing up here!

Amongst the latridiids, this species is really easy to ID because of those prominent protuberances on the elytra. There are 2 humps on the third row of elytral punctures and 2 smaller humps on the 5th row. This species is really common in many places and has been spread worldwide by human commerce.

Thanks Chris.
