Jurassic beaded lacewings (Insecta: Neuroptera: Berothidae) from Kazakhstan and Mongolia

Abstract

Two new genera and four new species of Berothidae (Berothone gen. nov., Krokhathone parva gen. et sp. nov., K. tristis gen. et sp. nov., Sinosmylites karatavicus sp. nov., and S. auliensis sp. nov) are described from the Upper Jurassic of Karatau (Kazakhstan). Sinosmylites hotgoricus sp. nov. is described from the Upper Jurassic of Khoutiyn-Khotgor (Mongolia). Intraspecific variation of Jurassic berothids, quantitative composition of the berothid fauna of Karatau, and records of the family from Jurassic and Lower Cretaceous deposits are discussed.
