New insect fossils discovered from the Lower Jurassic Sangonghe Formation at the Turpan Basin, Xinjiang, NW China
Résumé
Early Jurassic insects have been described from the Badaowan and the Sangonghe formations in the Xinjiang Uygur Autonomous Region, NW China. Among them, the insect fossils from the Sangonghe Formation remain poorly explored. Here we report for the first time a diverse assemblage of fossil insects from the Sangonghe Formation near the Daheyan Township, Turpan Basin. They are represented by six groups, including Odonatoptera, Dermaptera, Blattodea, Hemiptera, Coleoptera, and Diptera. Sinoscarterella incompleta Nel, Fu & Huang, gen. et sp. nov. of Dysmorphoptilidae (Hemiptera) and Liassorhyphus liaoi Nel & Huang, gen. et sp. nov. of Anisopodidae (Diptera) are described here. Our discovery provides a window into a potentially diverse entomofauna in the Early Jurassic, increasing our knowledge about the insect diversity during that time in eastern Asia.
