Tiny Tiny Fungus Beetle III - Malacocis brevicollis

Tiny Tiny Fungus Beetle III - Malacocis brevicollis
Near Ruraldale, Upshur County, West Virginia, USA
February 15, 2006
Size: 1.7 mm
High around 70 yesterday, a beautiful mid-February day to be out tramping around.

One of three images I'm posting (unlinked since there appear to be two or more individuals). My best bet is Minute Tree-Fungus Beetle, though a couple of other families seem possible too.


Ciidae: Malacocis?
Surely a Ciidae, but difficult to tell the species from frontal view... probably Malacocis brevicolis. Is this the same of the other two photos posted here??? If so, it's actually a Malacocis.

yes, pls move to Malacocis brevicollis
nice beetle, nice shot!

Almost certainly
There are some different individual beetles here, but they were all found in the same piece of fungus, so it seems almost certain they were of the same species. Thanks again for your help with these IDs, Cristiano.

it's not unusual for a bracket... be inhabited by several ciid spp. at a time; however, in my experience, they tend to represent different body size groups

Very ciid-like.
The somewhat hood-like pronotum, the large bugged-out eyes, and the three-balled antenna seen here are typical.
