TYPE LOCALITY: “ Liguria … prope Tergestum [ Liguria … near Trieste ( Italy )]” . TYPE MATERIAL: 1 ♂ , syntype (covered with mold) ( MZUF : Box 9): Gonia Mgn / interrupta Rnd. / 462. CURRENT STATUS: junior synonym of Onychogonia flaviceps ( Zetterstedt, 1838 ) ( Herting & Dely-Draskovits 1993: 261 , Cerretti 2010: 295 , O’Hara et al. 2020: 483 ). REMARKS: Rondani (1859b: 32) described Gonia interrupta from three specimens of both sexes: “ Unicum exemplar masculum … misit D. Mussino , et unicam forminam observavi collectionis Professoris Bellardi, et nuper specimen alterum maris a D. Schinero accepi [ D. Mussini sent a single male specimen, and I observed a single female in Professor Bellardi’s collection, and recently received another male specimen from Mr. Schiner ]”. We found just one male syntype in this study. The additional male and female syntypes have presumably been lost .
