青藏高原跳甲亚科昆虫区系研究

讨论青藏高原（包括横断山区）的跳甲亚科昆虫区系。该区已知47属228种。1）据属级阶元的分布类型分析，以东洋属和南型属种显占优势，是区系主体，显示该区跳甲区系的热带渊源，其中高山属种赋予该区以高山区系特征；2）该区物种分化活跃，是某些多种属中国种类的分布中心和分化中心；3）联系中国跳甲亚科区系，在地理分布格局上显示西－东分布，如Hespera属的分布和西南－东北分布或西南－东北的间断分布格局，如Pentamesa和Stenoluperus属的分布。这种地理分布格局反映青藏高原的隆起给中国昆虫区系带来重要影响。

THE ALTICINAE OF THE QINGHAI-XIZANG PLATEAUS (COLEOPTERA:CHRYSOMELIDAE)

This paper lists all the known species and genera of the subfamily Alticinae in the Qinghai\|Xizang Plateau, a total of 228 species belonging to 47 genera; and discusses their characteristics and distribution. At the generic level, the distribution of Alticinae in the Qinghai Xizang Plateau can be categoried into 5 types: 1) widespread in the world; 2) distributed in more than 3 zoogeographical regions; 3)distributed in two zoogeographical regions; 4)distributed in the Oriental or Palaearctic region; 5)restricted distribution, such as the East Asia area, or only in China or endemic to the Qinghai\|Xizang Plateau (Table 1). Except for widespread genera, East Asian genera and some genera endemic to China or to the Qinghai\|Xizang Plateau, the known genera in this region can also be divided into two types: the southern and northern genera. The southern genera and species comprise the main part of the Alticinae fauna of this region and reflect the tropical origin of this group. While at species level, we have classified the distribution into 2 distributional patterns: 1) a West East distributional pattern with the Hengduan Mountains Region as the first center of distribution e.g. the genus Hespera (Fig.1), the area of the Three Gorges of the Yangtze River as the second center and the Wuyi Mountains as the third; 2) Southwest Northeast distributional pattern, e.g. and Pentamesa which shows a discontinuous specific distribution from Xizang, Yunnan, Sichuan in China to Siberia in Russia and Korea. The genus Stenoluperus , a genus of the East Asia distributional component, shows two distributional centers, that is a southwest center and a northeast center, each center with its endemic species, or species of narrow and limited distribution but with widespread species such as S. nipponensis Lab. and S. flaviventris Chen linking the two centres of distribution.
