Stenomorpha marginata group, but not S. marginata
This is a very interesting area in Arizona for Stenomorpha. The marginal ridge/carina of the elytra, which is actually the R wing vein, and the degree of thickening and how it curves posteriorly along the elytra and if other wing veins are visible, with some other not so obvious characters would distinguish this from S. sponsor, as Casey would have put this pictured species above as S. rusticus. There are certain Stenomorpha species where the rugosity and punctation are more pronounced. The humeral angles, terminal antennal segments, posterior margin of the prothorax will vary from S. sponsor, otherwise this is just a population variation with S. sponsor. Without looking at it closely I would put this in Stenomorpha, but it is not S. marginata s.s.
