Update:
I found several of these at Cedar Bog again this year. The last one might be Hexatoma brevicornis, so if you have expertise, please D.

Note: I have photographed this Hexatomini at Cedar Bog in Champaign County, Ohio for at least 17 years. Always in the same area.
I've added two other observations; one from back in 2004.

Here's an observation this year (2022) with better pics of wing venation. Same location.

I found this site in 2020 but with this year's drought, there is a lot more exposed lakeshore and the plant (S! in MO) occurs in the millions of flowering and fruiting culms- only extant site in MO. It is the only sedge in MO that has white margins on the scales. Thus, the old name- Cyperus albomarginatus is more descriptive
See https://www.inaturalist.org/observations/807098 for another ear-tuft-less Abert's
The ID here is based on the AI suggestion an that I could find a a couple similar individuals in BugGuide of this species, but not of any other. This does not preclude it from being from another genus, though.

16 Jun 2015.
Buckingham Springs, Bucks Co, PA.
6.0 mm head-wingtips.
Attracted to porch light.
I don't think this is Metadelphax, but less sure about Muirodelphax. Or something else?
Shape and face color seem ok for S. magdalensis, but is the pronotum color ok?
Came to black light. I have lots and a variety of large bamboo around the borders of the yard.
Tentative ID; unfamiliar with this group, but ok match to BugGuide photos.
