Beetle - Airaphilus near-elongatus

I think this is something near Cucujidae, but any help at least on confirming a family is appreciated!

alright... let's provide it a temporary shelter then...
thanks for the update, Mike.

Moved from Airaphilus.

Another update
Dr. Halstead has had specimens of the Arizona Airaphilus for a month or so and I received this via snail-mail yesterday: "So far I have not got further with the Airaphilus from Arizona. I looked through the unnamed specimens in the Museum [of Natural History] and rechecked the named material but did not find the species. It is perhaps nearest/most similar to A. elongatus Gyll. (=geminus Kraatz) although differs in having a flatter, somewhat less robust head with different puncturation. I need to get hold of the original descriptions of one or two species described in the older literature for which I have little information apart from the reference. I'm still working on it!"

David Halstead confirmed it as an Airaphilus but could not identify it from the pictures that I sent and has requested that I send the specimen.

collected and sent to him by Eric Moody:

Moved from Beetles.

It is definitely Airaphilus!
There are 35 described species of Airaphilus, with the genus confined exclusively to the Old World. This constitutes a new hemisphere record. We have identified representatives of 10 of the species in the FSCA and several unidentified ones. I compared the specimen Eric Moody sent and it matches none of them.

I will send pictures of it to D.G.H. Halstead in England, the world authority on Silvaninae. Unfortunately, he does not have e-mail so the pictures will have to go the old-fashioned way and it will be some time before we get feedback.

In the meantime, I recommend collecting as many specimens as possible and documenting the habitat in detail.

I'd like to see your images, Michael.
Any chance you could post them on BG so we could link them to Eric's?


This is definitely getting exciting! Is there a chance it could be an introduced species?

I'll be back in the area in a couple weeks, and I'll certainly try to collect more when I'm there. What other sort of habitat info would be useful?

I've linked the head and full body shots.
This would be very cool if it's another completely undescribed species FOUND ON BUG GUIDE !!

What would you think
of sending a specimen for examination? Also, what was the beetle doing when you collected it? Was it under bark?

I'll send you an email so we don't clutter this page with discussion about shipping.

Your answer to Michael's question,
"What was the beetle doing when you collected it? Was it under bark?" would be very interesting if posted here I would think.

Moved from ID Request. We seem to have agreement that this is a beetle.

It certainly looks
"silvanidish," but I've never seen anything quite like it. It looks a bit like the genus Airaphilus, which is confined to the Old World. I suspect it is not a silvanid. What is the tarsal formula? Are the anterior coxal cavities closed or open? Can you get a better straight-on dorsal shot?


the mystery continues?
Tarsal formula appears to be 4-4-4 with open coxal cavities. Does this help narrow it down?

It excludes
it from the Silvanidae. The only genus in that family that is known to have a 4-4-4 tarsal formula is Uleiota, which this certainly is not.

Is it a colydiid? Perhaps a q
Is it a colydiid? Perhaps a quote from American Beetles might fit here..."If it has 4-4-4 tarsi and doesn't fit anywhere else, try this family" Though colydiids don't have filiform antennae...hmm...

facial features very un-colyd-esque

Anything else I can do to shed light on this mysterious beetle?

sending it to Mike Thomas is the best solution i can think of

looks like
something in Silvanidae to me....

antennae are off for a silv.; looks nice anyway
head closeup, please? beware of tenebs -- always!

the added shot makes you case, Guy!
must ask Dr Thomas...

I was gonna say this really looks like a silvanid to me, but nothing matches easily in AB...southern AZ...could be a new country record? Crossing fingers :)

found no match in BCA

Let me know if any additional shots would be helpful
