It is a member of Phyllotreta undulata group. In Italy three species: Ph. undulata (very common), Ph. vilis (rare) and Ph. christinae (rare).

Molte grazie Lech.
Obviously we hope that it is not that common .Looking at the pictures of P. undulata, I see that the pronotum has the punctuation much more marked; can be it a discriminating character?

Phyllotreta undulata is well distinguishable by punctation of frons forming only transverse band while in vilis and christinae whole frons is punctate (punctation forms triangular area). The best diagnostic characters are male genitalia.
