| Abstract: | A new false jewel beetle, Mesoschizopus elegans n. gen. n. sp., is described and illustrated based on a well-preserved impression fossil from the Lower Cretaceous Yixian Formation of China. It represents a definitive Mesozoic fossil belonging to the recent small buprestoid family Schizopodidae, which is now endemic to the western North America. Mesoschizopus is placed in Schizopodidae based on its overall body shape and size, short prosternum in front of procoxae, wide metanepisternum, and wing venation. The discovery of the first schizopodid from the Early Cretaceous not only highlights the antiquity of the small family, but also provides an example of a now narrowly distributed group whose ancestral groups were probably more widespread in the Mesozoic. |
