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 didn't do the best job taking pictures of key characteristics (such as wing venation), but I'm hoping somebody might be familiar with the striking color pattern. I'd love to know the species on this one.
