The beetle subfamily Curculioninae is part of the weevil family Curculionidae.

Given that the beetle order (Coleoptera) contains about one-quarter of all known organisms, the Curculioninae represent one of the – if not the – most successful radiations of terrestrial Metazoa.

Delimitation of the Curculioninae is fairly robust considering its enormous size; there is some dispute, however, in their exact boundary with the Molytinae.

These, as well as the Ceutorhynchinae, are sometimes included in the Curculioninae as additional tribes Cryptorhynchini and Ceutorhynchini.

And some genera while almost certainly Curculioninae, are too unusual and/or ancient to be easily assigned to a specific tribe.
