Trogidae 1416 - Bolitophagus corticola

Trogidae 1416 - Bolitophagus corticola
Camden, Knox County, Maine, USA
August 23, 2007

Something in Trogidae? The scutellum looks like it should be in Trox.

Moved

I can't see the tibial spurs
I can't see the tibial spurs that I see on Trogids, is that a good mark?

 
valid character
pretty much everything about the legs is different

not a Trogid
I can see why you thought so, but - start here

 
Bolito*phagus corti*cola?
Thanks for the direction. I didn't like my Trox guess vs Omorgus but thought the scutellum was more like that of Trox. Didn't even occur to me to look elsewhere though I realize now how obvious the mistake was. Ironically, the image of Tox, to which you chose to contrast, was one I took.

On a page you pointed me toward I found a link to an image of a Bolito*phagus corti*cola here that I think looks a whole lot better. FYI - about 6.5mm.

I don't see a guide page for this species, though, so one will have to be made if it's right.

 
Just realized that I had an e
Just realized that I had an email from a contributer who saw this image and suggested the same ID.

 
Does the scutellum have anything to do with it
I've noticed that the Trogids have the scutellum nearly circularl, whereas this is like a hemisphere.

 
not really
While this superficially resembles a Trogidae, it is in a completely different group - antenna for starters [can't see in this photo], tarsal formula, ad nauseum will differentiate the two. The scutellum is useful only for distinguishing Trox and Omorgus.

 
But...
You can't see any of that (whats a nauseum?0)... I guess this is where experience makes all the difference!

 
on and on ..
ad nauseam - perhaps not perfect use of phrase, but you get the idea.
compare tarsi

 
oh mother of....
I can't believe I asked what "a nauseam" was... I feel reallly dumb

 
How do you think I feel?
I wasn't even in the right superfamily. At least you had the sense to questione my bad guess.
