弱蛛科蜘蛛个体小，迁徙能力弱，是研究物种分布格局的好材料。弱蛛科蜘蛛主要分布在3个区域，其中美洲有65种、欧洲75种、亚洲132种。但亚洲的弱蛛科蜘蛛数量实际上远远高于美洲和欧洲的数量，仅在申请人目前的标本收藏中，就有130余个新物种有待描述和发表。本申请项目拟通过Turbo-taxonomy的方法首先发表这150个弱蛛科蜘蛛新种(含10多个欧洲新种)，在此基础上基于分子生物学方法研究弱蛛科蜘蛛起源和时空变化格局。同时进一步探讨弱蛛科蜘蛛分化机制，以发现东亚和东南亚的弱蛛物种数量差不多是其它地区4倍之多的进化动力。有关进化动力的研究，有助于我们阐明中国物种多样性的起源，说明中国成为生物多样性大国的原因。关于Turbo-taxonomy的尝试有助于解决物种描述的速度远远不能满足人们对物种认识和利用的日益增长的需要。

The spiders of family Leptoneidae are limited in migratory ability. They are mainly distributed in 3 regions, of which 65 species in American, 75 species in Europe and 132 species in Asia. In fact, the species number of family Leptoneidae in Asia is much more than in American and Europe. Only in our collection, there are more than 130 new species to be described and published. The current project is aimed to publish these new species based on turbo-taxonomy. The second goal is to study the diversification in space and time based on molecular data. The third goal is to study the power of diversification. The whole project can help us to understand why China is one of the mega-diversity countries.
