A new bark-gnawing beetle genus Sinopeltis gen. nov., with two species (S. jurrasica sp. nov. (type species) and Sinopeltis amoena sp. nov.), is described based on two well-preserved impression fossils. Specimens were collected from the Middle Jurassic Jiulongshan Formation in Daohugou Village, Shantou Township, Ningcheng County, Inner Mongolia, China from a lacustrine paleoenvironment, making it the oldest fossil of the family. Sinopeltis is placed into Peltinae incertae sedis.
