Rhynchaenus is a genus of beetles alternatively placed in the subfamilies Rhynchaeninae or in Curculioninae, of family Curculionidae.[1] [2] It previously included the genus Orchestes, but is now restricted to a smaller group of species, all of which occur in Europe, Japan, or North Africa and feed on Asteraceae plants.[3] Reports of its occurrence in North America are erroneous.[4]
A large number of species have been assigned under the Rhynchaenus genera although some species originally assigned to Rhynchaenus now belong in a different genera[5] [6]
