Rhamphini is a weevil tribe in the subfamily Curculioninae.
Weevils are beetles belonging to the superfamily Curculionoidea, known for their elongated snouts. They are usually small, less than 6 mm in length, and herbivorous. About 97,000 species of weevils are known. They belong to several families, with most of them in the family Curculionidae. Some other beetles, although not closely related, bear the name "weevil", such as the biscuit weevil, which belongs to the family Ptinidae.
Anthonomus is a genus of weevils. This genus includes major agricultural pests such as the boll weevil, strawberry blossom weevil, and pepper weevil, as well as promising biological pest control agents such as Anthonomus santacruzi.
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.
The insect tribe Stromboscerini is part of the weevil family Curculionidae, subfamily Dryophthorinae. It is a small and little-known weevil group. Alonso-Zarazaga & Lyal (1999) treated it as a subfamily.
Mononychus is a genus of minute seed weevils in the family of beetles known as Curculionidae. There are at least 20 described species in Mononychus.
Hainokisaruzo is a genus of Asian weevils, established in 2005 by Hiraku Yoshitake and Enzo Colonnelli. It includes several species formerly classified as Ceutorhynchoides spp. Several further species remain to be described.
Otiorhynchus is a large genus of weevils in the family Curculionidae. Many species of the genus, particularly the black vine weevil and the strawberry root weevil, are important pests, both as larvae and as adults. Larvae feed on plant roots. Adults are flightless with fused elytra and feed at night on plant foliage. In many species of the genus at least some races are polyploid and parthenogenetic, while the rest of the races and species are diploid and bisexual. Otiorhynchus weevils, particularly O. scaber, have been a popular subject for studies of the evolution of parthenogenesis. The genus is native to the Palearctic region. However, sixteen species were inadvertently introduced to North America and have become widespread there.
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.
Rhynchaenus is a genus of beetles alternatively placed in the subfamilies Rhynchaeninae or in Curculioninae, of family Curculionidae. 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. Reports of its occurrence in North America are erroneous.
Ceutorhynchini is a true weevil tribe in the subfamily Baridinae.
Ectemnorhinini is a weevil tribe in the subfamily Entiminae.
Ceutorhynchus elegans is a species of true weevils in the tribe Ceutorhynchini. It has a palaearctic distribution.
Auleutes is a genus of snout and bark beetles in the family Curculionidae. There are at least 30 described species in Auleutes.
Mogulones is a genus of minute seed weevils in the family of beetles known as Curculionidae. There are at least 30 described species in Mogulones.
Rhinoncomimus is a genus of minute seed weevils in the family of beetles known as Curculionidae. There are about eight described species in Rhinoncomimus.
Rhinusa is a genus of true weevils in the family of beetles known as Curculionidae. There are at least 20 described species in Rhinusa.
Mesagroicus is a genus of broad-nosed weevils in the beetle family Curculionidae. There are at least 40 described species in Mesagroicus.
Lepyrus is a genus of true weevils in the beetle family Curculionidae. There are more than 70 described species in Lepyrus.
Emphyastes is a genus of true weevils in the beetle family Curculionidae. There are at least three described species in Emphyastes.
Scleropterini is a tribe of minute seed weevils in the family of beetles known as Curculionidae. There are at least eight genera in Scleropterini.
