摘　　要：文中简述了襀翅目缅甸琥珀研究概况,并基于一件保存较好的雌虫标本,报道了襀翅目襀科新属种Burperla decolorata gen.et sp.nov.。该化石具有以下重要特征:体较长,体色浅,触须与触角较长,RP脉末端接近翅端部,下殖板宽大、圆形,后缘中部突出。这些形态特征显著区别于襀科的其它化石及现生类群。The stonefly fauna in mid-Cretaceous Burmese amber is reviewed.A new fossil stonefly,Burperla decolorata gen.et sp.nov.,is described and illustrated based on a well-preserved female specimen.This new taxon is characterized by the combination of the following characters:long and pale body,long palps and antennae,RA almost reaching wing apex,subgenital plate broad and rounded with a posteromedial projection.These morphological characters distinguish it from other extant and extinct stoneflies of Perlidae.
