异长足虻亚科的起源及演化(双翅目,长足虻科)

The Origiin and Evolution of the Subfamily Diaphorinae(Diptera,Dolichopodidae)

论文运用支系分类学的理论、原理与方法,通过寻找共近裔性状、祖裔关系、祖裔系列转换特征(共祖近度)、内、外群比较等重建了反映异长足虻亚科Diaphorinae的自然演化历史及其分类系统:2族、2亚族、4个属群,5个属亚群和14个属。文中含该亚科的系统发育树及根据系统发育特征建立的分族、亚族、属群、属亚群和属的检索表。

In this paper,the monophyly of Diaphorinae is proved by the structural features of male frons and face(fr/fa varies regularly)and hypopygium small and encapsulated,epandrium with single or double lobes apically etc.The patristic relationship of bifurcated or unbifurcated type,the regular changes in fr/fa and C,R 4+5,M,m-cu and r-m whether are normal or not,and the evolution of other related characters,a classification system reflecting the natural evolutionary history of this subfamily is established:2 tribes,2 subtribes,4 genera groups 5 genera subgroup and 14 genera.
