摘要: 根据已知世界上不同层位和地质时代产出的直脉蝎蛉科(Orthophlebiidae)分类的根据,本文进行了系统整理和总结,提出新的分类方案,即保留该科下的2个属直脉蝎蛉属(Orthophlebia)和原直脉蝎蛉属(Protorthophlebia),取消中蝎蛉属(Mesopanorpa);中蝎蛉属被取消后,Rs1至少带3支支脉的种,归入直脉蝎蛉属,Rs1仅带2支支脉的种,归入原直脉蝎蛉属;Rs1 2的共柄2倍长于Rs3 4的特征,本文不将其作为属和亚属的分类根据,具有该特征的种归入Rs1 2共柄长于Rs3 4的亚属。将Rs1 2分支早于、迟于或等于Rs3 4的特征作为亚属的分类根据,在直脉蝎蛉属和原直脉蝎蛉属下各自新建3个亚属。Abstract: Based on Orthophlebiidae occurring in different horizons and geological ages in the world,a generic taxonomy is emended systematically.The genera Orthophlebia and Protorthophlebia are retained in the family Orthophlebiidae,and the genus Mesopanorpa is can
