Saw sawyer beetles subfamily (Prioninae) Coleoptera Cerambycidae Cerambycidae (Coleoptera) in a small subfamily, but many of these species is an important pest in agriculture and forestry production. This paper describes the saw beetle subfamily economic significance and research status at home and abroad for lack of saw beetle subfamily study, focus on the the subfamily adult external morphological characteristics hind wing vein characteristics and male and female genitalia and China saw sawyer beetles subfamily insects Characteristics of Flora, the main results are as follows: 1. Adult external morphology of this thesis combines the latest saw germari subfamily Classification of view, improve China saw beetles subfamily classification system. Discovered two new species: Aegolipton yunnanensis Feng et Chen, 2007 Yunnan Mao-horned beetles Sarmydus trichodes Feng, et Chen, 2006 hair flat angle beetles, a new record in China is a Prionomma White, 1853 proposed soil longicorn genus and a new record in China species Prionomma bigibbosus White, 1853 Two Abrupt intends to soil sawyer beetles. Supplement the Bandar, Casiphia, Aegosoma, Palaeomegopis Aegolipton Psephactus, Psilotarsus Hystatoderes, Drumontiana Baralipton Megobaralipton Spinimegopis 12 genera and 57 species of Chinese morphological characters described so far, our country saw sawyer beetles subfamily known group 6, 22 genera, 94 species and subspecies. Think saw longicorn genus scientific name should be used Prionus Geoffroy, 1762,, rather than Prionus Fabricius 1775, because The Geoffroy proposed for the first time saw sawyer beetles is the scientific name Prionus. Preparation of the saw germari subfamily with Family retrieval table 6 family belong keys and 22 genera Key to Species. 2. Hind wing veins the study Saalas (1936) saw beetles subfamily named on the basis of the wing veins, according to Kukalova and Lawrence (2004) Coleoptera eat more of the suborder wing veins naming system, after the saw germari Subfamily wings The veins were renamed. Detailed description of the saw beetle subfamily 5 families, 12 genera, 24 species and subspecies of the hind wing veins characteristic of all ethnic groups, genera, species hind wing vein characteristics were compared, the hind wing vein characteristics found in sawing the the beetle subfamily family level, is the level and species level taxonomic significance. Summed up the hind wing vein characteristics saw beetles subfamily family level, is the level and species level taxonomic significance. 3 genitals to study the papers dissected saw beetles subfamily Group 4, 7 genera, 13 species and subspecies of female genitalia and Group 5, 9 genera, 20 species and subspecies of male external genitalia, a detailed description of its characteristics and to draw and shooting a feature map. Through a comparative analysis found that male and female genitalia saw beetles subfamily family level, is level and species level taxonomic significance. Summed up the saw sawyer beetles subfamily family level, the genus and species level taxonomic significance of the male and female genitalia Study on the Flora listed China saw sawyer beetles Subfamily directory, and have been documented in China are discussed as a basis for analysis 22 genera, 94 kinds of distribution in the the zoogeographical division and the administrative division, found that saw germari subfamily each genus, species distribution in China range of very different distribution of Physical Regionalization and administrative divisions saw beetle subfamily Category also, Macao Special Administrative Region (SAR) has not yet saw the beetle subfamily insect distribution record. The country saw sawyer beetles subfamily Japan ingredients dominant. Single distribution component, spanned distribution ingredient less. Endemic to China is also more abundant, Casiphia Fairmaire, 1894 is endemic to China, only distributed in southwest China. Endemic to China up to 40 species, accounting for 42.6% of the total of known species, of which 31 kinds of areas endemic. The study found that a serious shortage survey on saw germari subfamily Insect Resources in China. Chongqing is only recorded 6 saw beetles subfamily insects, significantly less than the Sichuan (already documented 23 species) and Guizhou (has documented 13 species).
