This one was surprisingly straightforward to identify. The lack of a sclerite at the base of the lateral hump narrows the field quite a bit, and the other options followed fairly obvious characteristics to Clostoeca, which only has one species, Clostoeca disjuncta.

When I tie the nymph I try to add the hind wing -all rumpled up inside the exuvia. That bit of realism turns those persnickety ones into biters, especially when fished deep. ;)

Tabled is a good idea. I feel like I'm intruding on an old established poker game without my cigars. The picture is beautiful. I came across a video that might lighten up the conversation. Although I did learn a lot from www.FlyfishingEntomology.com and Taxon.
Here is the video http://tinyurl.com/k9kwj8e
