A taxonomic monograph of the genus Solariola Flach, 1908 (Coleoptera: Curculionidae: Entiminae)

: 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.
