Can you rule out Chlaenius emarginatus?
Image suggests (?) elongated mandibles, a character state of subgenus
Anomoglossus
. Recording body length is always helpful.

You are correct
on both counts. I can't rule it out and I really do need to start paying attention to size of insects.

See my additional comments
under the close-up image of mandibles. I suggest that these images be eventually frassed for the simple reason they are ambiguous for two common species which are already well typified at BugGuide. Thanks for trying.

Good points except:
1. These appear to be the only images for this genus currently representing Iowa on BugGuide. They may be common but Iowa is the most biologically altered state in the US. I figure if a species can be found in Iowa then certainly it can be found most anywhere in its range.
2. I actually use BugGuide as my data base reference (until the day I truly get organized which at my age may never happen) for small parcels of land I manage.
I either have to kill an insect or photograph them. With a dead voucher in hand I have a reference for ID. But with a photo I use BugGuide as the ID reference.
You're an expert and I am not. Suggestions are welcome.

Both
Take a picture then collect it. By having a voucher specimen, you will have an accurate ID for a species photographed in nature, plus you can donate the specimen to a person/group working on that species. You in turn, help the scientific community by donating a specimen and contributing the knowledge derived from it.
There are several of us who would love to receive voucher specimens for our work and help get you accurate IDs: Joshua Basham (Buprestidae), Peter Messer (Carabidae) and myself (Elateridae), just to name a few.
P.S...if a species-level ID can be confirmed, I'd keep these images in BugGuide :) I personally like to see state and temporal data added to BG.
