Thanks for posting this.
I have something from WI that keys to C. auritus in Van Dyke (1932) but I had nothing to compare it with. Mine is similar in pronotal coloring and pronotal punctation. My specimen has predominately dark elytra, with only reddish on the humeri, but several of these Conoderus can have a variety of color forms.
My specimen has noticeable carina on the hind angles, slightly diverging from the lateral edge. I think I can see carina in yours, but it's kinda hard with a straight-on dorsal shot.
Another characteristic of auritus is the membranous lobe on the tarsal segments are not broad and readily visible above the tarsi. I can't quite see that in your ventral shot but I can in my WI specimen.

Agreed
Mine has carina as you described, and the tarsal lobes are narrow.

Thanks
Other than elytral coloring (which can vary in several Conoderus spp.) this matched well with my WI specimen and the key in Van Dyke (1932).
