Short summary
Dascillidae are a species-poor beetle group with a scarce fossil record. Here, we used light microscopy and X-ray microtomography to describe Baltodascillus serraticornis gen. et sp. nov. based on a well-preserved specimen from Eocene Baltic amber. We tentatively place this species in the subfamily Karumiinae. This is the first representative of the Dascillidae formally described from Baltic amber and the first described fossil member of the subfamily Karumiinae.
