Sitonini is a tribe of weevils in the Entiminae subfamily. There are currently 9 extant genera, and one fossil genus, Sitonitellus . [1]
The Curculionidae are the family of the "true" weevils. They are one of the largest animal families, with 6,800 general and 83,000 species described worldwide.
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.
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.
The Entiminae are a large subfamily in the weevil family Curculionidae, containing most of the short-nosed weevils, including such genera as Otiorhynchus, Phyllobius, and Sitona. Some of these weevils are notorious pests of major economic importance.
Entimus is a genus of broad-nosed weevils belonging to the family true weevil and the Entiminae subfamily.
Entimus splendidus is a species of broad-nosed weevils belonging to the family true weevil and the Entiminae subfamily.
