The fossil record of the Prenolepis genus-group is comprehensively reviewed for the first time. Five fossil species are presently known from this clade: Nylanderia vetula, sp. nov. (Dominican amber); Nylanderia pygmaea, comb. nov., Prenolepis henschei and Pseudolasius boreus (Baltic and other contemporaneous amber deposits); and Protrechina carpenteri (Arkansas amber). With the reclassification of Nylanderia pygmaea, it is now clear that the major lineages of the Prenolepis genus-group existed by at least the Eocene.
