Thanks for looking at this for me Brady. I have to admit I was doing some guessing as I went throught the key (Merritt et al.), since the 7th pair of gills are missing.
I noticed in the key that in Ecdyonurus, the pale spots between the antennae are missing, and abdominal terga are usually without a distinct contrasting color pattern.
I wonder if it might be Nixe?
