Emergence of a superradiation: pselaphine rove beetles in mid-Cretaceous amber from Myanmar and their evolutionary implications

Pselaphinae is an exceptionally species‐rich, globally distributed subfamily of minute rove beetles (Staphylinidae), many of which are inquilines of social insects. Deducing the factors that drove pselaphine diversification and their evolutionary predisposition to inquilinism requires a reliable timescale of pselaphine cladogenesis. Pselaphinae is split into a small and highly plesiomorphic supertribe, Faronitae, and its sister group, the...
