''Sitona'' is a large genus of weevils in the family Curculionidae native to the Nearctic and Palaearctic regions. Over 100 species have been described.〔 ''Sitona'' is easily distinguished from related genera by flat, recumbent scales on the mandibles, by the absence of an oval scar on the mandibles, by short and broad rostrum with a deep, longitudinal, median groove, and by dense scales on the body.〔Donald E. Bright, Patrice Bouchard. ''The Insects and Arachnids of Canada'', Part 25: ''Coleoptera. Curculionidae. Entiminae. Weevils of Canada and Alaska''. Vol. 2. Ottawa, NRC Research Press, 2008. ISBN 0-660-19400-7. P. 178-203.〕 ''Sitona'' specialize on legumes, plants of the family Fabaceae. The larvae eat the root nodules〔Korortyaev, B. A. and A. J. Velázquez de Castro González. (2011). (A new species of the weevil genus ''Sitona'' Germar (Coleoptera: Curculionidae) from Mt. Hermon in Israel. ) ''Proceedings of the Zoological Institute RAS'' 315(1) 85-88.〕 and the adults eat the leaves. Several species of ''Sitona'' are important agricultural pests of legumes, especially in its native regions and introduced populations in South Africa, Australia and New Zealand. Species include: *''Sitona aliceae''〔Velázquez de Castro, A. J., et al. (2011).
