A new well-preserved genus and species of fossil Glaphyridae (Coleoptera Scarabaeoidea) from the Mesozoic Yixian Formation of Inner Mongolia China

摘要

A new genus and species of fossil Glaphyridae, Cretohypna cristata >gen. et sp. n., is described and illustrated from the Mesozoic Yixian Formation. This new genus is characterized by the large body; large and strong mandibles; short labrum; elytra without longitudinal carina; and male meso- and possible metatibia apically modified. A list of described fossil glaphyrids of the world is provided. This significant finding broadens the known diversity of Glaphyridae in the Mesozoic China.
