I cannot easily place this specimen, the punctures on the abdomen seems far too fine and dense for C. impressa, as does the quite narrow apical rim. The coastal location, punctuation, red sternites and white hairs makes me think of C. rutiliventris, but it seems less "particular" than that species. Have very limited experience with C. rutiliventris, in the Nordics the blue colour is very dark, almost black, but chrysidids do get lighter as you go south.
If you have a picture showing the distance between the compound eye and the mandible joint it could be of help, but mostly to rule out species, not to actually find which one it is.
The ignita-complex needs a review in central and southern Europe, Paolo has re-instated the species rank in some described species recently, there's undoubtedly more synonyms to discover, and new species.
