A New Agyrtid Beetle (Coleoptera, Agyrtidae) from the Lower Cretaceous Khasurty Locality

The first fossil monotypic genus of the subfamily Necrophilinae (Coleoptera, Agyrtidae), Palaeonecrophilus buryaticus gen. et sp. nov., is described from a positive and negative imprint found at the Early Cretaceous Khasurty locality in Western Transbaikalia. The beetle is similar to modern Necrophilinae in the presence of notches on the apical antennomeres and the wide and flattened edges of the pronotum. It is distinguished from the modern species by the strong anterior protrusion of the anterior pronotal angles and the oblique orientation of the metanepisterna. Widely spaced anterior coxae with a process between them distinguish the new species from the representatives of the genus Necrophilus. Palaeonecrophilus presumably fed on carrion, like modern Necrophilus and Zeanecrophilus.
