Tenebrionid? - Stenomorpha

Tenebrionid? - Stenomorpha
Pima Canyon, Santa Catalina Mts., Pima County, Arizona, USA
September 26, 2006
Size: ~20mm
Looks like a Tenebrionid. After 20 guide pages, the most similar are of the genera Scotobaenus and Iphthiminus. Can anyone narrow it down - ID please.

Moved from Beetles.

Nice pic!
Nice picture--probably Stenomorpha marginata, but there are some people revising the genus right now, and the nomenclature is likely to change in the next few years.

 
Stenomorpha revision
AS luck would have it, I am revising the genus of Stenomorpha. I am doing a molecular and morphological systematic revision. So if you want to collect any beetle that looks similar to the one in your picture and toss them in 95% ethanol and ship them off to UC Davis Entomology, Bohart Museum, Fran Keller, that would be great and help me tremendously.
There are many "subspecies" of Stenomorpha marginata and I am trying to determine if they should all just be one species or elevate them to valid individual species. Any mailing info can be found on my CV on my webpage. Lats and longs with collection data are great too because I am mapping where individuals are collected for all 95 Stenomorpha species.
And yes the nomenclature will probably change and hopefully when I am done with my thesis I'll have an interactive key online with pictures and easy steps to identify to species.

 
Thanks Fran
I am currently working on Padre Island Sea Turtle Project and will return to Tucson mid July.

 
Thank you!
Thanks for the confirmation on the genus, and a probable species.

Same as

 
this one? not Stenomorpha
this one?http://bugguide.net/node/view/77992/bgimage looks like an Asidine but not a Stenomorpha sp.

 
Looks close
enough to be a congener at least. Mine is not as flat across the "elytra." Subtle difference in "lip" encircling abdomen; yours seems a little more raised. These may be variable characters and have nothing to do with beetle ID - just musing. I take it, you never got it down to genus/species?

Stenomorpha?
Might be Stenomorpha. As luck would have it, got some of these in Molino Canyon Vista as well, and will check them against the U of AZ collection, eventually. Nice image, as always.

 
Thanks
Eric - let me know what you find out.
