Tragidion annulatum
This is a male specimen, not a female. The male is the paler of the two and has the annulate antennal segments. I've seen this species many times in lower Madera Canyon.

Exactly
it seems to me a nice T. peninsulare Schaeffer 1908.

If I read the source correctl
If I read the source correctly annulatum was the original name and is still used for the Southwest population, whereas peninsulare is a later split-off for the California and Baja populations. In the Specimen photo of the source the label stil shows 'annulatum var. peninsularis'. Wouldn't that put our AZ specimen into the annulatus group?

agreed
I've been following M&H [pg 153] for the latest nomenclature.
