In this view, we can see a small appendage extending from the tip of the abdomen. This small and tiered structure is her postabdomen or Female terminalia. (compare to the previous image) Thanks for confirming this John!
There is a drawing of these female parts, (of a related genus) in the key, but this was the first time that I had seen the living structure, in this family. Otherwise, I wouldn't have included these dim images.
