Hi Piluca,
beautiful pictures, again!
You specimen is very interesting. I would say Chrysis ignita group.
Since the pronotum is very narrow, I think that this species is closely related to Chrysis rutiliventris Abeille.
In Spain there's an interesting subspecies, called valenciana Hoffmann, 1935, which could fit your specimen (for sure not lusitanica Mocsary, which is a different taxon).
Nice finding!
Let's see if our Nordic colleagues have some better ideas,
Cheers
Paolo
