The beetle subfamily Curculioninae is part of the weevil family Curculionidae. It contains over 23,500 described species in 2,200 genera, and is therefore the largest weevil subfamily. 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.
Dryophthorinae is a weevil subfamily within the family Curculionidae. While it is not universally accepted as distinct from other curculionid subfamilies, at least one major recent revision elevated it to family rank, as Dryophthoridae
The tribe Rhynchophorini is the largest member of the true weevil subfamily Dryophthorinae. Alonso-Zarazaga and Lyal (1999) treated it as a distinct subfamily, Rhynchophorinae. Weevils of this tribe have the pygidium not covered by the elytra.

Ophryastini is a weevil tribe in the subfamily Entiminae.
Polycatini is a weevil tribe in the subfamily Entiminae.
Polydrosini is a weevil tribe in the subfamily Entiminae.
Zygopini is a tribe of twig and stem weevils in the beetle family Curculionidae. There are more than 20 genera and at least 250 described species in Zygopini. 83 species are currently known from the 11 genera occurring north of South America, 8 genera occur exclusively in South America, and 2 are recorded from Africa.
Notiodes is a genus of marsh weevils in the beetle family Erirhinidae. There are about 16 described species in Notiodes.
Conoderinae is a subfamily of true weevils in the beetle family Curculionidae. There are more than 210 genera in 15 tribes, and about 2,400 described species in Conoderinae.
Rhinoncomimus is a genus of minute seed weevils in the family of beetles known as Curculionidae. There are about eight described species in Rhinoncomimus.
Tychiini is a tribe of leguminous seed weevils in the family of beetles known as Curculionidae. There are about 5 genera and at least 30 described species in Tychiini.
Conotrachelini is a tribe of true weevils in the family of beetles known as Curculionidae. There are about 7 genera and at least 50 described species in Conotrachelini.
Piazurini is a tribe of true weevils in the beetle family Curculionidae. There are about 12 genera and more than 400 described species in Piazurini.
Othippiini is a tribe of true weevils in the beetle family Curculionidae. Of the eight genera in Othippiini, only Egiona and Othippia are not monotypic. Acoptus suturalis is the only species of the tribe found in the New World.
Rhinostomus frontalis is a species of weevils, previously placed in a genus called Yuccaborus and known as the yucca weevils.
