Staphylinoidea is a superfamily of beetles. It is a very large and diverse group with worldwide distribution.

Contents

Characteristics

Most staphylinoids are middle-sized or small beetles with a pair of shortened elytra. The hind wings have no accessory posterior ridge (locking device), no wedge cell and apical cell. Abdominal 8th segment not entirely invaginated in the 7th. Head mostly without coronal suture.

Systematics and evolution

Staphylinoidea contains the following subgroups:

  • Agyrtidae C.G. Thomson 1859
  • Hydraenidae Mulsant 1844
  • Leiodidae Fleming 1821 = (Anisotomidae)
  • Ptiliidae Erichson 1845
  • Cephaloplectinae or Limulodidae Sharp 1883
  • Scydmaenidae Leach 1815
  • Silphidae Latreille 1807 (carrion beetles)
  • Staphylinidae Latreille 1802 (rove beetles)

    • The unambiguous fossil record dates back to Triassic, and an early Mesozoic origin of the group is probable.
