Crypto*phagidae? - Pteryngium crenatum

Crypto*phagidae? - Pteryngium crenatum
Jefferson Notch area, Coos County, New Hampshire, USA
May 12, 2007
Size: about 1.7 mm
I found three tiny beetles of this presumed genus (possibly species) on the undersides of three fresh, moist conks growing on standing dead conifers, along with a scattering of spri*ngtails about their size. This is the all-testaceous one.

fungus:
colour variable.

beetle: please save! (guess will turn out to be what I told)

 
I will save you any cryptophagid you like.
I know they are not Don's favorite group :-)

Moved from Beetles.

Yes.
Elongate body, pronotal margin slightly serrate but with no other features, and roaming on conk´s underside fit for genus Pteryngium.

conk species = Fomitopsis pinicola? - would strengthen ID some more.

 
P. crenatum...
...seems to be the only recognized NAmer sp., accg. to AmBeetles 2:341

 
Excellent!
I'll move it to species page.

 
That looks like it.
The ones I found had a little wider band of red on top but otherwise the same as your image.
