白垩纪中期贾氏缅甸蚊蝎蛉(昆虫纲:长翅目)新材料
New materials of Burmobittacus jarzembowskii(Insecta:Macroptera)from the mid-Cretaceous
摘要
Abstract
The earliest fossil records of Bittacidae can date back to the Triassic,with a higher diversity during the Jurassic,and lower diversity in the Cretaceous.This paper based on four well-preserved new specimens of Bittacidae from the mid-Cretaceous Kachin amber in Northern Myanmar(Hukawng Valley),revised the diagnosis of Burmobittacus Zhao,Bashkuev,Chen & Wang,2017,supplemented the features of head,the basal part of the wing,and genitalia of Burmobittacus jarzembowskii Zhao,Bashkuev,Chen & Wang,2017,indicated a significant difference in the intraspecific length ratio between radial sector(Rs)and R2+3.This paper also compiled a fossil genus-level key for the Bittacidae and compared the wing differences among fossil groups of Bittacidae from Mesozoic.关键词
