Entiminae
The Entiminae are a large subfamily in the weevil family Curculionidae, containing most of the short-nosed weevils, including such genera as ''Entimus'', ''Otiorhynchus'', ''Phyllobius'', ''Sitona'', and ''Pachyrhynchus, Pachyrrhynchus''. In comparison with their stunning diversity, only a few of these weevils are notorious pest (organism), pests of major economic importance. Entimines are commonly encountered in the field, including urban environments, and abundant in entomological collections. Diversity There are over 12,000 described species in the Entiminae subfamily worldwide, distributed in over 1,370 genera, which total nearly 14,000 by more recent counts. Most tribes are represented in only one biogeographic region of the world. The current classification within the subfamily has been recognized as artificial rather than reflecting natural groups. General morphology Besides the shape of their broad and short rostrum, most entimines are easily recognized by the prese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sitona
''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 mandible (arthropod), mandibles, by the absence of an oval scar on the mandibles, by short and broad rostrum (anatomy), rostrum with a deep, longitudinal, median groove, and by dense scales on the body.Donald E.
