: Chrysis impressa.

This is one of the most common species of the Chrysis ignita-group. The hosts are Eumeninae of the species Ancistrocerus parietinus and A. quadratus. The species is very difficult to separate from closely related species. Guidelines for identification include that the puncture of T2 is gradually finer towards the hind margin, and T3 of the female is typically sadle-shaped.
