Do I dare to question Kimsey's identification? Yes I do. With four teeth at the end of abdomen there is no way it can be Caenochrysis (which has three teeth or no teeth). It is clearly genus Chrysis but I would not dare to say any species name.

PS. There are two different genera in bugguide: Trichrysis and Caenochrysis. Trichrysis is not pesent in New World, where Caenochrysis is found. I suggest that all photos under genus Trichrysis here should be moved to the Caenochrysis. Or alternatively all Caenochrysis should be placed under Trichrysis if some older system is followed and current taxonimy is ignored. Anyway you can't have both unless you have some old world Trichrysis species also here.

Not sure it's sharp enough, though. Thanks for your help.
