The species has been photographed in Italy (you), Spain, France south and north, England south and last week Netherlands.
Main difference is the colouring of the thorax, and there is a subtle difference in the white hairs close to the border of the wing. Latipennis also is significantly bigger than rothschildi, at least 25%. Last friday I'v pictured 16 latipennis and 1 rothschildi at the same scale.
Yours definitely is latipennis!
