A new stem bythinine in Cretaceous Burmese amber and early evolution of specialized predatory behaviour in pselaphine rove beetles (Coleoptera: Staphylinidae)

Comprising more than 10,000 valid species, the staphylinid subfamily Pselaphinae is a major element of epigean habitats, and among the most diverse groups of rove beetles. Pselaphinae is split basally into two principal clades: the small supertribe Faronitae, and its sister group, the hyper-diverse ‘higher Pselaphinae’ containing the remaining five supertribes. Deducing the origins and divergence times of major higher Pselaphinae clades requires...
