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.

I keyed this specimen to Paragnetina, and range maps would seem to rule out every species of that genus except for the common Paragnetina media.
