Staphylinoidea

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

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.[1]

Systematics and evolution

Staphylinoidea contains the following subgroups:[2][3][4][5]

  • Family Agyrtidae C.G. Thomson 1859 (primitive carrion beetles)
    • Subfamily Agyrtinae Thomson, 1859
    • Subfamily Necrophilinae Newton, 1997
    • Subfamily Pterolomatinae Thomson, 1862
  • Family Hydraenidae Mulsant 1844 (minute moss beetles)
    • Subfamily Hydraeninae Mulsant, 1844
    • Subfamily Ochthebiinae C. G. Thomson, 1860
    • Subfamily Orchymontiinae Perkins, 1997
    • Subfamily Prosthetopinae Perkins, 1994
  • Family Leiodidae Fleming 1821 (round fungus beetles)
    • Subfamily Camiarinae Jeannel, 1911
    • Subfamily Catopocerinae Hatch, 1927
    • Subfamily Cholevinae Kirby, 1837
    • Subfamily Coloninae Horn, 1880
    • Subfamily Leiodinae Fleming, 1821
    • Subfamily Platypsyllinae Ritsema, 1869
  • Family Ptiliidae Erichson 1845 (featherwing beetles)
    • Subfamily Acrotrichinae Reitter, 1909
    • Subfamily Cephaloplectinae Sharp, 1883
    • Subfamily Nanosellinae Barber, 1924
    • Subfamily Ptiliinae Erichson, 1845
  • Family Silphidae Latreille 1807 (carrion beetles)
  • Family Staphylinidae Latreille 1802 (rove beetles)

The unambiguous fossil record dates back to Triassic, and an early Mesozoic origin of the group is probable.[6]
