Cysteodemus - Cysteodemus wislizeni

Cysteodemus - Cysteodemus wislizeni
Petroglyphs National Monument, Albuquerque, Bernalillo County, New Mexico, USA
July 31, 2004

Moved

Just browsing the Meloid pages -
and yes, I think this is Cysteodemus wislizeni. There are only these two species in the western US. Body shape and color differ from armatus (see here:1 ).

Moved

Neat beetle,
leaving a little reminder of its passage I see ;-)

Checking the BISON species list for New Mexico I find only one member of this species, Cysteodemus wislizeni (look under "Beetle, Blister (Cysteodemus wislizeni)"), which is reported for Bernalillo County. On what basis did you determine the species? If it was just that it was close in general appearance, this image should be moved back to genus level. On the other hand, if there were special traits that differentiate this beetle from Cysteodemus wislizeni, please explain in detail since the image is too fuzzy for much ID determination.

 
Think I goofed
You're right, I think I just misread a reference. Looking here and here, it looks like there's some difference in the structure of the thorax(?). I can't see anything that looks wider like in armatus in the photo but the angle isn't the best and I'm only guessing that that's a valid characteristic.
I'll move it to Cysteodemus although it probably is wislizeni.
