Can we get to genus?

Moved from Caenochrysis.
This is not a Caenochrysis, instead it is Chrysis and I am sure of it, otherwise I would not disagree with Kimsey. The identification of this one as Caenochrysis is based solely on three teeth at the end of abdomen. Actually if observed from this angle you can not see if there are three or four teeth, I think there must be four teeth but only two of them are visible. If it was Caenochrysis then it should not have dorsal thorax that rounded, instead it should be rather flat with posteriorly projecting metanotum. Also the face is never that flat with Caenochrysis. It looks like typical member of the Chrysis ignita species group.

Caenochrysis sp. -- det. L.S. Kimsey
Moved from Chrysidini.

We can get to tribe...
At any rate. This small jewell belongs to the Chryisidini, that is either to genus Chrysis or a very closely related one. I would lean for a true Chrysis, but with no conclusive proof.

Thanks Richard

This may officially be the best image of a chrysidid yet:-) If Trichrysis is still a valid genus, then that is where this specimen belongs (three teeth on the rear of the abdomen).

Thanks Eric.
