Narrowing species possibilities
From the relatively short ovipositor (i.e half the wing length or less) this can be narrowed down to one of G. assectator, G. kirbii, or G. amputatum. The last of those can be eliminated since it has a white tip on the ovipositor and its range is southern Arizona into Mexico. If you can carefully measure the length-to-width ratios of the 2nd hind tarsus and the 4th antennal segment...and can consistently correlate that with the sheen (shining or matte) of the may be able to get to species (for details, see here).
