Hylobius (Callirus) transversovittatus (Goeze, 1777)

Curculio transverso-vittatus Goeze, 1777: 396 .

Curculio brunonianus Ponza, 1805: 61 syn. n.

Curculio brunonianus Ponza was listed by Sherborn (1924: 916), neglected again in subsequent catalogues of Curculionidae, and considered a nomen dubium by Alonso-Zarazaga et al. (2017: 538). Its type was destroyed already before publication (Ponza 1805: 39, footnote). Dutto et al. (2009: 428) pointed out that an anonymous hand-written note on a copy of Ponza’s (1805) paper refers this name to Hylobius fatuus (Rossi, 1790), which is a synonym of H. transversovittatus (Goeze, 1777) (Alonso-Zarazaga et al. 2017) . From this and the original description, we formally synonymize C. brunonianus Ponza, 1805 with H. (Callirus) transversovittatus (Goeze, 1777) (new synonymy).

In Italy, H. transversovittatus occurs across most of the mainland regions and in Sicily (Abbazzi & Maggini 2009). In this country, from a conservation point of view, the species is classified as “Least Concern” (Colonnelli & Gatti 2015) but, in reality, is it becoming very rare and even disappearing from many localities (E. Colonnelli, unpublished data).
