Derobrachus? - Derobrachus - female

Derobrachus? - Derobrachus - Female
Las Cruces, Doña Ana County, New Mexico, USA

Size: 60 mm
Was thinking either P. californicus or P. lecontei at first. Now I'm thinking it might be more likely that it's Derobrachus.

Moved from Prionus.

Derobrachus sp.

Any features
That I could shoot to get to a species level? I've got the specimen.

I think eye placement
but can't remember if dorsal or ventral. I think (don't hold me on this), D. geminatus has the eyes touching on the underside and D. hovorei does not. Compare eye placement with others in the guide. There is a recent revision too you can check.
