I can’t figure out what this is.
Your assistance is appreciated.
We photoed this guy at Homolovi State Park, Arizona.
It was October.

This is a Darkling Beetle, and we believe it is in the genus Philolithus, and we found an image on BugGuide of Philolithus sordidus that looks similar and an image on BugGuide of Philolithus morbillosus that also looks similar. The former species has a greater range, and Philolithus morbillosus is only reported from Arizona on BugGuide. In the past two days, Tenebboy has been identifying many unidentified Darkling Beetles in our archive, and we will see if he can provide an accurate identification on your Darkling Beetle.
You are very generous with your time and expertise. Thank you. If you further refine your identification I am eager to hear!
