Sorry...

to make you play yo-yo with this one, but I'd like you to move it to Maccaffertium. I can't find any examples of male Leucrocuta with eyes that fluoresce all the way to white in bright light. Based on the white on the mesoscutellum, I would guess that this is probably M. pulchellum or M. modestum (which is a highly variable species).

No problem

I'm happy that you just don't give up and ask me to frass :-)
Thanks

Probably Leucrocuta

After looking this over a number of times, I think I am now sufficiently convinced that it is Leucrocuta. (My best guess is that it might be juno based on the coloration and rather fine cross veins, but it is hard to be sure.)

Male heptageniid

The dark background makes it a bit hard to see the wing venation/markings, but this is a male imago of Heptageniidae. It doesn't seem to have the marking in the third space near the bulla that would be the telltale for Stenacron. The separation of the eyes at the vertex suggest that this is probably Maccaffertium or Leucrocuta. This is where size might help. If it was around 6-9mm, Leucrocuta would be likely. If it was 9mm or larger, it is probably one of the Maccaffertium.
