Sister‐group relationships are resolved for the systematically and biogeographically puzzling austral rove beetle genus Hyperomma by means of phylogenetic analysis of five gene markers (one mitochondrial and four nuclear protein‐coding) for 25 taxa broadly representing the subfamily Paederinae, and six outgroup taxa from Staphylininae and Pseudopsinae. As a result, the new subtribe Dicaxina subtrib. nov . is established for Hyperomma and five other Southern Hemisphere genera previously classified in Cryptobiina. Based on the molecular phylogeny and the discussion of several adult and larval morphological characters, the concept of the tribe Paederini is changed as follows: Paederini sensu novo is reduced to include Paederina, Cryptobiina, Dolicaonina and Dicaxina only, while Lathrobiini sensu novo is established for Lathrobiina, Scopaeina, Astenina, Stilicopsina, Medonina, Stilicina and Echiasterina. The tribe Cylindroxystini stat. resurr . is reinstated for the Paederini subtribe Cylindroxystina because of its very peculiar morphology not fitting either Paederini or Lathrobiini in new sense. The tribe Pinophilini was resolved as sister to Lathrobiini sensu novo , and its status remains unchanged. Morphological diagnoses and other relevant systematic information are provided for all newly established taxa. The taxonomic history of the higher‐level systematics of the subfamily Paederinae is summarized.
