Abstract

A new aeschnidiid dragonfly, Gansuaeschnidia hongi gen. et sp. nov., is established based on three hind wings from the Lower Cretaceous Chijinpu Formation of the Jiuquan Basin, northwestern China. The new taxon is characterised by the strongly closed Ax1 and Ax2, only one row of cells in the lower and middle parts of the discoidal triangle, and subdiscoidal area not divided by a clear AAspl vein. This new discovery indicates that the Chijinpu Formation can be correlated with the Yixian Formation, i.e. the second evolution stage of the Jehol Biota, adding to the diversity of the aeschnidiid dragonflies in China during Early Cretaceous. All taxonomic acts established in the present work have been registered in ZooBank (see below), together with the electronic publication LSID: urn:lsid:zoobank.org:pub:2D4DC1B7-1F6C-481C-A07E-A4CB82C8012F.
