Very Unusual Underbark Denizen - Phymaphora pulchella - male - female

Very Unusual Underbark Denizen - Phymaphora pulchella - Male Female
Near Ruraldale, Upshur County, West Virginia, USA
May 5, 2005
Size: Maybe 4 mm
Tiny, tiny beetle. I took me a little while to realize there were two of them. They were cojoined, in fact. The female was noticeably smaller.

I'm always a little sheepish when I can't even figure out the family. What's going on with those antennae? Is that a huge ball cap on the end of the antenna? It reminds me of the photo not long ago of the pseudo-scorpion hitch-hiking on an insect's antenna. Any way I am stumped here. Interesting shape of the pronotum, but that didn't help me find the ID. Any help appreciated!

to species page.

Phymaphora pulchella
There is an eastern and western species, with the eastern one being P. pulchella.

This is a handsome fungus beetle in the family Endomychidae. I think this is a male. I collected something similar many, many years ago in Oregon, and I have the genus name somewhere. Will try and get that to you. Neat bug!

Genus Phymaphora.
Pretty certain this is a species of Phymaphora, or something closely related. Males have the enlarged, flattened antennal segments.

Thanks again, Eric
Thanks again, Eric. After you supplied the genus name I found the same or very similar species on the Cedar Creek site: insects/album/024081013ap.html

I looked back through Dillon and Dillion to see if I had missed it on my first pass through, but no, it just wasn't there.
