Hister Beetle, dorsal - Euspilotus
Montosa Canyon, Santa Cruz County, Arizona, USA
July 26, 2013
Size: 3.47 mm
Download high resolution image here.

I found this beetle a few inches from the opening of a burrow, most likely that of a rodent, in an open field next to the dry bed of the Santa Cruz River where it crosses Mount Hopkins Rd. during Bugguide Gathering 2013. I have tentatively keyed it to Geomysaprinus in Arnett(1), based on the images linked here. Expert confirmation and species ID are appreciated.

This image is from a CombineZP processed set of 118 images with a 23 µm step taken with a Nikon CFI LU Plan Fluor 5×/0.15 ∞/0 mm microscope objective + Nikon 200 mm F/4 AIS telephoto lens + Nikon D300 camera (magnification 5×; technique described here).

Moved from Geomysaprinus.

William B. Warner responds, "That is a new species of Euspilotus I am in the process of describing along with a few other saprinines from AZ."
