Lixinae is a subfamily of true weevils,〔Bouchard P. et al. (2011) (''Family-group names in Coleoptera (Insecta).'' ) ZooKeys 88:1-972〕 included in the Molytinae in many older treatments. They are mainly root feeders, although some develop in flower buds or stems. Several species are used in biological control of invasive weeds, namely knapweeds (''Centaurea''). Characteristics include tarsal claws that are fused at the base, and labial palps are short and telescoping. The body is elongate shape, as for some other weevils. Each tibia bears an uncus (small hook) on its distal end. The rostrum is forwardly directed. == Taxonomy == There are three tribes.〔〔; 1999: ''A world catalogue of families and genera of Curculionoidea (Insecta: Coleoptera) (excepting Scolytidae and Platypodidae)''. Entomopraxis, Barcelona. (PDF )〕 The largest of these by far are the Cleonini, sometimes ranked as an independent subfamily in the past: Cleonini * ''Adosomus'' * ''Afghanocleonus'' * ''Ammocleonus'' * ''Aparotopus'' * ''Aplesilus'' * ''Apleurus'' * ''Asinocleonus'' * ''Asproparthenis'' * ''Atactogaster'' * ''Bodemeyeria'' * ''Bothynoderes'' * ''Brachycleonus'' * ''Calodemas'' * ''Centrocleonus'' * ''Chromonotus'' * ''Chromosomus'' * ''Cleonis'' * ''Cleonogonus'' * ''Cleonolithus'' * ''Cnemodontus'' * ''Coniocleonus'' * ''Conorhynchus'' * ''Cosmogaster'' * ''Curculionites'' * ''Cyphocleonus'' * ''Entymetopus'' * ''Eocleonus'' * ''Epexochus'' * ''Ephimeronotus'' * ''Epirrhynchus'' * ''Eumecops'' * ''Eurycleonus'' * ''Georginus'' * ''Gonocleonus'' * ''Hemeurysternus'' * ''Heterocleonus'' * ''Isomerops'' * ''Koenigius'' * ''Leucochromus'' * ''Leucomigus'' * ''Leucophyes'' * ''Liocleonus'' * ''Lixocleonus'' * ''Lixomorphus'' * ''Lixopachys'' * ''Mecaspis'' * ''Menecleonus'' * ''Mesocleonus'' * ''Microcleonus'' * ''Mongolocleonus'' * ''Monolophus'' * ''Neocleonus'' * ''Nomimonyx'' * ''Pachycerus'' * ''Pajnisoodes'' * ''Paraleucochromus'' * ''Pentatropis'' * ''Phaulosomus'' * ''Pleurocleonus'' * ''Pliocleonus'' * ''Porocleonus'' * ''Priorhinus'' * ''Pseudisomerus'' * ''Pseudocleonus'' * ''Pycnodactylopsis'' * ''Resmecaspis'' * ''Rhabdorrhynchus'' * ''Rungsonymus'' * ''Scaphomorphus'' * ''Stephanocleonus'' * ''Surchania'' * ''Temnorhinus'' * ''Terminasiania'' * ''Tetragonothorax'' * ''Trachydemus'' * ''Trichocleonus'' * ''Trichotocleonus'' * ''Whiteheadia'' * ''Xanthochelus'' * ''Xenomacrus'' * ''Zaslavskia'' Lixini * ''Broconius'' * ''Eugeniodecus'' * ''Eustenopus'' * ''Gasteroclisus'' * ''Hololixus'' * ''Hypolixus'' * ''Ileomus'' * ''Lachnaeus'' * ''Larinus'' * ''Lixus'' * ''Microlarinus'' * ''Microlixus'' * ''Mycotrichus'' Rhinocyllini * ''Bangasternus'' * ''Rhinocyllus'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lixinae」の詳細全文を読む スポンサード リンク
