First Fossil Click Beetles from the Middle Jurassic of Inner Mongolia, China (Coleoptera: Elateridae)

Abstract. A new genus with two new species and one new species of fossil elaterids are described: Paradesmatus baiae sp. nov., Paradesmatus ponomarenkoi sp. nov., Protagrypnus robustus sp. nov. These findings document the fossils from the Middle Jurassic Jiulongshan Formation of Eastern Inner Mongolia, China. Fossil elaterids of Mesozoic with large triangular plates of metacoxae have been discovered only from the Upper Jurassic strata of Karatau so far, Paradesmatus baiae with the unique feature will expand our knowledge on the early diversification of elaterids.
