Abstract

The odonatan asiopterid Turanopteron sinensis sp. nov. and the juragomphid Oxfordgomphus trescellulae gen. et sp. nov. are described on the basis of two new fossil wings from the Middle-Upper Jurassic of Henan Province in China. These taxa belong to ancient, Toarcian epiproctophoran stem groups of Anisoptera Selys, 1854. They show important affinities with taxa from the Karatau entomofauna in Kazakhstan. These groups progressively decrease and were replaced by more modern clades of Anisoptera during the Late Jurassic.

摘要

基于来自中国河南省中晚侏罗世的两块新化石翅片，描述了蜻蜓目亚洲古蜓科的中华图兰蜓（新物种）和侏罗原蟌科的三细胞牛津原蟌（新属新物种）。这些分类单元属于古的、托阿尔阶上肛附器类的1854年塞利斯差翅亚目干群。它们与哈萨克斯坦卡拉套昆虫区系的分类单元有重要的亲缘关系。在晚侏罗世期间，这些类群逐渐减少，并被更现代的差翅亚目分支所取代。
