Hedychridium buyssoni or jucundum? Italy

[briang]

21 June 2023. Val d’Arda, N Apennines, Italy. Last year I posted a poor image of a Hedychridium that Paolo said was probably buyssoni or jucundum, but it was impossible to go further. I am now posting a better image of what looks like the same species, but only one viewpoint. Is it possible to choose between these two names, or might it be neither? Any advice very welcome!
