Congratulations Frank,
in a very short time you became a real expert!
All you ID are correct.
I can only add:
Hedychridium:
- Hedychridium sp. (femoratum ?) is H. jucundum (it has a large black spot on T2, but femora and tibiae are metallic, not yellowish)
- Hedychridium sp. (Spain) should be a male of H. incrassatum (with a swelling on apical margin of T3)
- Chrysis succincta ? (from Spain). It belongs to this group, but there are two small teeth on the apical margin of T3. It could be C.griboidi (I don't have material to compare with), but there are other similar species there. I need to check it.
- Chrysis ignita group: it seems a Chrysis ruddii
Cheers
