A revision of the genus Solariola Flach, 1908 of the tribe Peritelini Lacordaire (1863) (Curculionidae: Entiminae) which includes forty-three species is completed. According to morphological characters and distribution, the species are divided into three informal groups (the number of species ascribed to the group is in brackets). These are the Solariola doderoi group (15), the Solariola gestroi group (14) and the Solariola paganettii group (14). We present keys for the identification of the genus among the Palaeartic Peritelini and keys to identify all species groups and species. Distribution maps and data on ecology and phenology are also provided. In addition to the following nine species already belonging to the genus we list 34 new species as well: Solariola gestroi (A. F. Solari, 1903), Solariola paganettii (Flach, 1905), Solariola doderoi A. F. Solari (1923), Solariola hirtula (A. F. Solari,1923), Solariola vitalei A. F. Solari (1923), Solariola ruffoi Osella Di Marco (1996), Solariola angelae Baviera (2015), Solariola fraterna Baviera (2015), Solariola pesarinii Baviera (2015); Solariola angelinii Bellò, Osella Baviera sp.n., Solariola benellii Bellò, Osella Baviera sp.n., Solariola bucolorum Bellò, Osella Baviera sp.n., Solariola cajetanibelloi Bellò, Osella Baviera sp.n., Solariola calida Bellò, Osella Baviera sp.n., Solariola comata Bellò, Osella Baviera sp.n., Solariola diottii Bellò, Osella Baviera sp.n., Solariola fancelloi Bellò, Osella Baviera sp.n., Solariola forbixi Bellò, Osella Baviera sp.n., Solariola gratiensis Bellò, Osella Baviera sp.n., Solariola hyblensis Bellò, Osella Baviera sp.n., Solariola ientilei Bellò, Osella Baviera sp.n., Solariola margaritae Bellò, Osella Baviera sp.n., Solariola mariaeclarae Bellò, Osella Baviera sp.n., Solariola mariaesilvanae Bellò, Osella Baviera sp.n., Solariola mariaetheresiae Bellò, Osella Baviera sp.n., Solariola melonii Bellò, Osella Baviera sp.n., Solariola nemoralis Bellò, Osella Baviera sp.n., Solariola normanna Bellò, Osella Baviera sp.n., Solariola obsoleta Bellò, Osella Baviera sp.n., Solariola pacei Bellò, Osella Baviera sp.n., Solariola paulimagrinii Bellò, Osella Baviera sp.n., Solariola pentaphyllica Bellò, Osella Baviera sp.n., Solariola petriolii Bellò, Osella Baviera sp.n., Solariola poggii Bellò, Osella Baviera sp.n., Solariola raphaelis Bellò, Osella Baviera sp.n., Solariola rosae Bellò, Osella Baviera sp.n., Solariola sabellai Bellò, Osella Baviera sp.n., Solariola saccoi Bellò, Osella Baviera sp.n., Solariola sbordonii Bellò, Osella Baviera sp.n., Solariola selinusia Bellò, Osella Baviera sp.n., Solariola tedeschii Bellò, Osella Baviera sp.n., Solariola venusta Bellò, Osella Baviera sp.n., Solariola zoiai Bellò, Osella Baviera sp.n..
