We can rule out all of our Nothochrysinae (Nothochrysa & Pimachrysa) given the green coloration, lack of an orange head, and their significantly different wing venation. We can rule out Leocochrysini (Leocochrysa) as the only western member has rather different wing venation as well. And it isn't either of our 2 Belonopterygini as this doesn't have a shortened prothorax. So definitely Chrysopini.

Ceraeochrysa is ruled out per below. The facial markings don't align with any of our species of Chrysopa, Kymachrysa, or Nineta in range. The marked scapes and body rule out any Chrysoperla. Antennal scapes aren't structured right for most Meleoma as they aren't strongly and atypically cylindrical. It doesn't align with any of the Pseudomallada species either. And we only get a single species of Plesiochrysa in Florida.

By process of elimination, that should just leave Eremochrysa and Yumachrysa (or one of the Meleoma with more Chrysopa-like scapes). Both are most speciose in (and around) Arizona as well.

This doesn't appear to be any of the species of Ceraeochrysa reported in the US and may well be out of range of the genus. There are various species of the desert southwest that won't key out in the Stange key to Floridian genera and tend to be a bit lesser known. I'd presume one of the other genera of Chrysopini.
