Hadramphus stilbocarpae, commonly known as the knobbled weevil, is a species of weevil in the family Curculionidae . Endemic to New Zealand, it was first described by Guillermo Kuschel in 1971. [1]
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. Approximately 97,000 species of weevils are known. They belong to several families, with most of them in the family Curculionidae. It also includes bark beetles, which while morphologically dissimilar to other weevils in lacking the distinctive snout, is a subfamily of Curculionidae. Some other beetles, although not closely related, bear the name "weevil", such as the biscuit weevil, which belongs to the family Ptinidae.
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.
Caridae is a small Gondwanan family of weevils. They are considered part of the primitive weevil group, because they have straight rather than geniculate (elbowed) antennae. The insertion of the antennae on the rostrum cannot be seen from above. Caridae also lack spiracles on abdominal tergites 6 and 7. The prothorax lacks lateral carinae. It has been suggested that the fossil weevil Eccoptarthrus belongs in this family, which would result in a change in the family name ; this proposal has been rejected by most coleopterists (e.g.)
Cryptorhynchinae is a large subfamily of weevils (Curculionidae), with some 6000 species. They are found in most zoogeographic regions although they are most diverse in the Neotropics, Australia and Oceania.
Nemonychidae is a small family of weevils, placed within the primitive weevil group because they have straight rather than geniculate (elbowed) antennae. They are often called pine flower weevils. As in the Anthribidae, the labrum appears as a separate segment to the clypeus, and the maxillary palps are long and projecting. Nemonychidae have all ventrites free, while Anthribidae have ventrites 1-4 connate or partially fused. Nemonychidae lack lateral carinae on the pronotum, while these are usually present, though may be short, in Anthribidae.
Hadramphus, commonly known as knobbled weevils, is a genus of flightless molytine weevils from the family Curculionidae. It is endemic to New Zealand and consists of four species.
Anagotus stephenensis, commonly known as the ngaio weevil, is a large flightless weevil that is only found on Stephens Island in New Zealand. The ngaio weevil was discovered in 1916 by A.C. O'Connor on Stephens Island. Thomas Broun described it in 1921 as Phaeophanus oconnori after its collector. The weevils were observed at the time to be 'feeding on tall fescue and the leaves of trees'.
Anagotus fairburni or Flax weevil is a large flightless weevil. It feeds on leaves of New Zealand flax species where it produces a characteristic feeding notch. It is found on islands and in alpine areas of New Zealand.
Rhamphini is a weevil tribe in the subfamily Curculioninae.
Eustylini is a primarily Neotropical weevil tribe in the subfamily Entiminae.
Didymus metrosideri is an endemic weevil from the Kermadec Islands in New Zealand. This species was discovered by W. L. Wallace during the 1908 Kermedec Islands expedition.
Hadramphus spinipennis, commonly called the coxella weevil, is a large, nocturnal, flightless weevil only found on Mangere and Rangatira Islands in the Chatham Islands, New Zealand.
Lissorhoptrus is a genus of rice water weevils in the family of beetles known as Erirhinidae. There are at least 20 described species in Lissorhoptrus.
Linogeraeus is a genus of flower weevils in the family of beetles known as Curculionidae. There are at least 60 described species in Linogeraeus.
Mesoptiliinae is a subfamily of true weevils in the family Curculionidae. There are at about 23 genera and 40 described species in Mesoptiliinae.
Micromimus is a genus of true weevils in the beetle family Curculionidae. There are about 18 described species in Micromimus.
Hilipinus is a genus of pine weevils in the beetle family Curculionidae. There are at least 50 described species in Hilipinus.
Lyperobius huttoni is a New Zealand weevil found in alpine areas of the South Island and at sea level around the Wellington coast. It feeds only on speargrass (Aciphylla). Weevils from the endangered Wellington population have been translocated to predator-free Mana Island.
Premnotrypes is a genus of weevils. It was described in 1914 by American entomologist W. Dwight Pierce (1881-1967). Several species in the genus are pests, because the larvae feed on potato tubers and the adults on the leaves. It is native to Latin America, in particular Bolivia, Colombia, Ecuador and Peru, but has been recorded as a possible invader on other continents.
Hadramphus pittospori, is a species of weevil in the family Curculionidae. Endemic to New Zealand, it was first described by Guillermo Kuschel in 1987.
