The discovery of the hindwing of the Early Cretaceous dragonfly Sinaktassia tangi Lin, Nel & Huang, 2010 (Odonata, Aktassiidae) in northeastern China

摘要

A well-preserved female hindwing of the petalurid dragonfly Sinaktassia tangi Lin, Nel & Huang, 2010 is described from the Lower Cretaceous Yixian Formation of Inner Mongolia, China. The discovery of this hindwing allows to complete the description of this Chinese Cretaceous taxon, provides distinctive features from other Aktassiidae, and indicates a comparatively wide distribution of this dragonfly in northeast China.
