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.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

I photographed three strange striped Ephemerella nymphs from the same trip on the same river: a black and olive one, a brown one, and this one. I have tentatively put them all in Ephemerella needhami for now.
