Dissoleucas niveirostris (Fabricius, 1798)

Anthribus niveirostris Fabricius, 1798: 160 .

Curculio ? dubius Ponza, 1805: 65, pl. 1, Lin. 3[.3]

Hoffmann (1945: 148) apparently was the first to recognize C. dubius Ponza as a junior synonym of D. niveirostris (Fabricius) [as Tropideres (Enedreutes) niveirostris]. The name is a junior primary homonym of C. dubius Strøm, 1783 and therefore permanently invalid. It was overlooked by previous cataloguers despite its original placement in Anthribidae: "Ad Anthribos D. Geoffroy certe referendum. Curculiones inter, et Attelabos medium tenet locum." (Ponza 1805: 65).

Dissoleucas niveirostris is widespread in Piedmont and is recorded from all Italian regions, Aosta Valley excepted (Abbazzi et al. 2001; Norbiato & Bartolozzi 2017).
