摘要
西双版纳、滇西北、西藏高原3个区域的斑腿蝗科区系成分比较结果表明,各区域的蝗虫组成各有特色,属种数量由多到少依次为西双版纳、滇西北、西藏高原。特有种均十分丰富,特有物种数及其比例以西藏高原为最高,西双版纳次之,滇西北最低。3个区域的斑腿蝗科昆虫在体型、翅型、体色变化等方面有不同的适应表现,总趋势是随海拔升高,翅退化强烈、体型趋小、体色加深。突出的是西藏高原特有种类的分布区非常狭窄,物种分化现象十分明显。推断西双版纳可能为斑腿蝗科物种的现代分布中心,滇西北为过渡地带。
To analysis and compare faunal components of Catantopidae among Xishuangbanna, the northwestern Yunnan and Tibet plateau, the result shows that faunal components are different among the three areas. Numbers of genus and species of Catantopidae are the most abundant in Xishuangbanna, the smallest in Tibet Plateau. Besides, the endemic species that distribute in the three areas are very abundant, numbers and proportion of the endemic species increase successively in the northwestern Yunnan, Xishuangbanna and Tibet Plateau. With elevation become higher, Catantopidae insects have different adaptive expression on their body forms, wing forms and body colours. The overall trend is that with elevation become higher, wing retrogression become more violent, body form become smaller and body color become darker. It is outstanding that the endemic species of Tibet Plateau which are specialized evidently have narrow and limited distribution zoon. It can deduced that the northwestern Yunnan is a transition zone, and Xishuangbanna is a modern distribution center of Catantopidae present species among those areas.
