A friend has given to me some boxes of wasps (He studied Vespidae, Pompilidae, Spheciformes, Chrysididae, and other small families, especially in Franche-Comté - France, between 1965 & 1990).
I found a Chryside of the west of France : Bourgneuf, Loire Atlantique, 16 VII 1978. (on a costal dune).
-> my first ID was Chrysura laodamia iphimedeia (Trautmann). (Chrysura group simplex with the parallel gena).
-> but I found a small & vestigial TFC (transverso frontal carina).
could be Chrysis gracillima or Chrysis subsinuata (I found mediocris with Berland).
What do you think ?
