Mayfly - Heptagenia marginalis

Mayfly - Heptagenia marginalis
Sharon/Housatonic Meadows State Park, Litchfield County, Connecticut, USA
September 26, 2015
Size: 9.5mm
I know the wing venation is important to see but I'm not sure what else. I have several photos of this individual so if any other features are needed to id please let me know and I'll see if I have it. I can also attempt to do some modifications with light and contrast to make the wing venation a little more clear.
