Tragidion - Tragidion densiventre - Male Female
Molino Basin, Catalinas, Pima County, Arizona, USA
September 27, 2007
There were red males and females and caramel colored ones of both sexes. The caramel colored ones had the banded antennae. The males had nobbs on the side of the pronotum that were nearly missing in females, the females had a clearly fuzzy, velvety pronotum. The pronotum of the males only shows very short hairs under the magnifying glass.

I'm inclined to believe...
...these are Tragidion densiventre, based on the narrow black basal band on the elytra. This species occurs in lower desert habitats, while T. deceptum occurs at higher montane elevations, although to two species can co-occur (even feeding on the same shrubs) in zones of contact.
