What I see is consistent with
Rhagio. Is that a ventral shot of the end of the abdomen? The only illustration I have is dorsal.
Rhagionidae are common fossils, for whatever that is worth. The family has traditionally been a dumping ground for diverse unspecialized Tabanomorpha. It probably contains several lineages that diverged in the Jurassic.
