I know this is a robber fly but after looking in your guide, there were so many kinds I could not narrow it down.

Efferia?
I'm thinking this is a female Efferia, as they have those long, blade-like ovipositors. I do not know if that is a genus-specific character, though, so you should wait for Herschel Raney to add a note before moving this image to a guide page.

Efferia
Yes, this is Efferia, in the Nerax group and likely aestuans.
