摘要： Raphidioptera (snakeflies) are the least diverse order among extant Holometabola, representing relicts of their rich Mesozoic paleofauna. Baissopteridae are one of the two major lineages from the Mesozoic, but with a poorly known evolutionary history. Here, we report the first fossil record of Baissopteridae from the mid-Cretaceous of Myanmar, represented by a diverse assemblage including 10 new species in six genera:Allobaissoptera oligophlebiagen. et sp. nov.,Baissoptera burmanasp. nov.,B. maculatasp. nov.,B. monopodasp. nov.,B. pankowskiorumsp. nov.,B. wangisp. nov.,Burmobiassoptera jiaxiaoaegen. et sp. nov.,Electrobaissoptera burmanicagen. et sp. nov.,Rhynchobaissoptera huigen. et sp. nov., andStenobaissoptera xiaigen. et sp. nov. The new Cretaceous baissopterids provide significant morphological evidence in favor of the monophyly of this family. The morphological diversity in these Cretaceous baissopterids, particularly with some specialized and unique characters, highlights the early radiation of snakeflies formed in the complex tropical forest ecosystem of the mid-Cretaceous.
