Unknown Beetle - Trogloderus

Unknown Beetle - Trogloderus
Moab, Grand County, Utah County, Utah, USA
August 15, 2005
Size: 3/8"
This critter was on the porch railing at night. Didn't seem bothered much by me or the camera.

Moved
Moved from Darkling Beetles.

Trogloderus
This is in the genus Trogloderus, subfamily Opatrinae.

Tenebrionidae: Glyptasida sp?
I think it is a Glyptasida. I could be wrong - it could be something close to Glyptasida.

Tennebrionid
The heavy-armored darkling beetles replace ground beetles to a great extent in the dry western/southwestern region, and this beetle certainly resembles many a dry-area darkling beetle.

Tenebrionidae?
My educated guess would be Tenebrionidae, but I too am not sure.

Trogidae
Looks like member of the family Trogidae, but Im not sure, if it is, my guess would be genus Trox

 
Youre right
After checking again Im gonna support the Tenebrionid theory. Sorry, Im only used to the beetles here in the east, and my first reaction was trogidae, due to texture and shape. But the legs look a bit too long for the trogids out here, and darklinng beetles do have rather lengthy legs.

Sorry for the misID...
