Rhinocyllus Rhinolarinus new subgenus new species Cirsium Italy


The species belonging to the weevil genus Rhinocyllus are studied. A new species, Rhinocyllus alpinus sp. nov. living on the inflorescences of Cirsium alsophilum (Pollini) Soldano (Asteraceae), is described from the central Italian Alps. A new subgenus, Rhinolarinus subgen. nov., is created for this new species. The following new synonymy is proposed: Curculio inquilinus Gyllenhal, 1827 syn. nov. of Rhinocyllus conicus (Froelich, 1792). Lectotypes for Curculio inquilinus Gyllenhal, 1827, Rhinocyllus olivieri Gyllenhal, 1835 and Rhinocyllus oblongus Capiomont, 1873 are designated. Due to lack of type specimens and information subsequently to its description, Rhinocyllus turkestanicus Desbrochers des Loges, 1900 is considered as species incertae sedis. Keys to the subgenera and to the species of Rhinocyllus s. str. are provided and taxonomical differences are illustrated.

Key words: Rhinocyllus, Rhinolarinus, new subgenus, new species, Cirsium, Italy
