Evolution of Mastigitae: Mesozoic and Cenozoic fossils crucial for reclassification of extant tribes (Coleoptera: Staphylinidae: Scydmaeninae)

Mastigitae is a supertribe of ant-like stone beetles (Scydmaeninae) that includes over 40% extinct genera, and whose evolutionary history is documented from the Upper Cretaceous through to today. Based on the results of phylogenetic analyses combining the most extensive taxon sampling to date, we reclassify Mastigitae into six monophyletic units: Leptomastacini, Clidicini sensu nov., Papusini trib. nov., Leptochromini trib. nov., †Baltostigini...
