Definitely something in Harpalus subgenus Pseudoophonus
If I had to guess I'd say either pensylvanicus or compar, but I can't see the pronotum hind angles well enough to tell.
Josh, in case you're curious what excludes your other guesses, here are some of the more obvious characters: all Amara have two setae beside each eye, harpalines have just one; Notiobia never have extensive punctation on the bottom of the pronotum as seen here; Selenophorus have many setae-bearing punctures on several elytral striae; Stenolophus ochropezus is much smaller and the pronotum is much less wide relative to height.

Pseudophonus
Thanks Curt, That was very useful information. I added one picture that is a bit more laterally oriented, however it is still too dorsal to see any of the ventral pronotum.

if measurements are accurate
maybe Harpalus caliginosus (or something else in that subgenus), although gestalt grabs me for something in Pseudoophonus.

Re Harpalus caliginosus
In the info section BG has Harpalus caliginosus as 18-26mm, which would be bigger if that info is correct.

thanks
I'll let the carabid guys confirm but for retention in the Guide I'd suggest returning the original pic w/o the ruler :)
