It is a junior primary homonym of Gyrinus urinator Illiger, 1807: 299 , and thus Drapiez’s name is permanently invalid. The identity of this taxon might be objected because the author did not mention the bronzed shiny longitudinal stripes on the elytra; however, the yellowish brown ventral surface together with the type locality ( Piedmont , Italy ) leave no doubt that the species Drapiez studied is in fact G. urinator Illiger. Thus , Drapiez’s name is not only a homonym but also a junior subjective synonym of Illiger’s name.
