I wonder if all of these are the same species, but I don't know the exact range for Rhamphomyia nasoni.
Rhamphomyia: (Kansas)

 
Rhamphomyia nasoni
I think you are right. I looked at the only four photos for this species. Two appear similar to my contributor's (Alfredo Colon) photo, but they do not show the abdomen. The other two show the abdomen, but it appears more "black and white" than Alfredo's photo. However, the half smokey wings may be the clincher. No other photos of any dance flies that I saw show half smoky wings. Or did I miss one?
