The Glossosomatidae are a family of the class Insecta and order Trichoptera.The family contains 23 genera in three subfamilies.〔Tree of Life Web Project. 2010. Glossosomatidae. Version 20 July 2010 (temporary). http://tolweb.org/Glossosomatidae/14582/2010.07.20 in The Tree of Life Web Project, http://tolweb.org/〕 In the US alone, there are 76 spp. in 6 different genera.〔Merritt, RW, Cummins, KW, Berg MB. (2008). An Introduction to the Aquatic Insects of North America, 4th ed. pp. 443, 446-448, 451-454, 460, 470-473〕 Glossosomatids, commonly known as the Tortoise or Saddle-Case Makers, and are worldwide in distribution. The common names were derived from the domed shaped cases created by the larvae.〔 The first species was described by John Curtis in 1843, but the family wasn't created until 1891 by HDJ Wallengren.〔The Taxonomicon.''Glossosomatidae''. Universal Taxonomic Services. 26 Jan 2014., http://taxonomicon.taxonomy.nl/TaxonTree.aspx?id=29372〕〔''Glossosoma Curtis, 1834''. Natural History Museum, http://www.nhm.ac.uk/research-curation/scientific-resources/biodiversity/uk-biodiversity/uk-species/species/glossosoma.html〕 ==Morphology== Larvae: Glossosomatid larvae have membranous meso- and metanotums (or if they do have sclerites, never more than half of the notum). They do not possess a prosternal horn. Their 9th abdominal segment has a sclerite. In addition, Glossosomatids tend to have short anal prolegs complete with accessory hooks.〔 Adults: Glossosomatid adults tend to be small to medium sized with long antennae, short fringed wings, and long palps. On their mesothorax, two round, hairy mesoscutellar warts, parallel to one another, can be found. Adults have 3 ocelli upon their head. Their maxillary palps are 5-segmented with the 2nd segment rounded, and as long as the 1st segment. Preapical spurs are not found on their fore tibia. Lastly, Glossosomatid adult have widely spaced mesal setose warts on their prothorax.〔 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「Glossosomatidae」の詳細全文を読む スポンサード リンク
