New Cupedids (Insecta: Coleoptera, Cupedidae) from the Lower Cretaceous of Buryatia

Two new species of cupedids (Notocupes khasurtyiensis sp. nov. and Gracilicupes minimus sp. nov.; Coleoptera, Cupedidae) are described from the Lower Cretaceous of Khasurty, Transbaikalia. This is the first discovery of the genus Gracilicupes in Russia, previously known only from the Middle Jurassic of China. New species are described from part and counterpart prints of nearly complete beetles.
