Aphodius sp.
Could be A. coloradensis. My references are at home, so I will have to check later. Note the ridging on the hind tibia, characteristic of Aphodiini. Aph. warneri is similar to A. coloradensis but is at lower elevations.

 
from Bill Warner
"I am leaning towards rudis because of clypeal shape & pronotal flaring (the locality is right too)--some females of rudis have the basal margin sinuation somewhat muted and pronotal punctures relatively fine compared to males--that basal margin is not clear in the photo, however. Those darned coffee-colored specimens from high altitudes always throw one for a loop!

If this is a Margarethe Brummerman specimen, have her bring it with her to Sullivan's party at the end of the month and I will take a look at it."

 
Ok, I'll try to bring it there

 
from Paul Skelley:
"Don’t know what else it could be other than P. coloradensis. The “flared” pronotum could simply be a lighting artifact. Those tibiae make it definitely an Aphodiini, and the setal fringe on the clypeus narrow it down to a few genera, for which most are red in color."

Again I can try to dig deeper later, just to confirm.

Eupariini...
Not an expert, but it looks similar to Martineziana dutertrei

 
Flared pronotum
and shape of head and clypeus really look like Martineziana sp. It behaves differently from an Aphodius, too. Runs around like a ground beetle.

 

 
flared pronotum..
doesn't look much like A. coloradensis (hence my hesitation) but the hind tibia are definately Aphodiini. Martizeziana is not in AZ (to my knowledge) and none of the AZ Eupariini have hind tibiae like this.

There are inquilinous Aphodius (s. lat.) with a flared pronotum. Several in AZ, too. As I said I can key this out later tonight or tomorrow, if someone doesnt get to it first.
