Last major gap in scydmaenine evolution filled (Coleoptera: Staphylinidae)

The tribe Scydmaenini represents one of the most successful modern groups of the ant-like stone beetles (Scydmaeninae), displaying a high degree of species diversity (>750 species) and morphological disparity. Surprisingly, direct fossil evidence crucial for elucidating the origin and early evolution of Scydmaenini is lacking. This gap of knowledge is of particular interest as the Cretaceous origin of other major scydmaenine lineages, e.g.,...
