beetle - Orchesia

beetle - Orchesia
Dixville, Coos County, New Hampshire, USA

Size: ~5mm
Is this some type of fungus beetle?

A tough one...
This appears to be a specimen of the family Melandryidae, the False Darkling Beetles. If it was found around fungus, this would definately help my belief. I found one picture that suggested it may be of the species Anaspis, but the text on the page was in german. I suspect that it is either a species of Anaspis, maybe a more slender species of Eustrophinus, or possibly a dark species of Orchesia, possibly O. castanea. There is also the possibility, giving that Melandryids are about the same size as members of the family Mordellidae, that it is a very large Tumbling Flower Beetle. Without a guesstimate on the size, though, I can't help much more.

I would say
Orchesia myself, but a statement of the size is critical, and if it is an Orchesia, a photo of the maxillary palpi would be necessary for further placement.

It's about 5mm. If I took the picture in closest focus, which I think I did, then that's an accurate size.

That is
within the typical size of an Orchesia. That would be the best placement.

Orchesia sp.
Thanks for all the help Don and Michael.
