Pemphredoninae

The subfamily Pemphredoninae also known as the aphid wasps,[1] is a large group in the wasp family Crabronidae, with over 1000 species. Historically, this subfamily has frequently been accorded family status. In some recent phylogenetic analyses, one of the subtribes within this group is the sister lineage to the superfamily Apoidea, and accorded family rank as Ammoplanidae along with Pemphredonidae and Psenidae so as to keep families monophyletic.[2]

  • Deinomimesa (Perkins, 1899)
  • Lithium (Finnamore, 1987)
  • Mimesa (Shuckard, 1937)

  • Nesomimesa (Malloch, 1933)
  • Odontopsen (Tsuneki, 1964)

  • Psen (Latreille, 1796)
  • Pseneo (Malloch, 1933)
  • Psenulus (Kohl, 1897)

The subfamily consists of solitary, parasitoidal wasps, each genus having its own distinct and consistent prey preferences. The adult females dig tunnels in the ground, or plant material, for nesting.[3]

As with all other sphecoid wasps, the larvae are carnivorous; females hunt for prey on which to lay their eggs, mass provisioning the nest cells with paralyzed, living prey that the larvae feed upon after hatching from the egg.

Subdivisions

In most classifications, the Pemphredoninae are divided into four tribes: Entomosericini, Odontosphecini, Psenini, and Pemphredonini; the last of which has by far the largest number of species. The primary distinction between the Psenini and the Pemphredonini is that Psenini have a forewing with three submarginal cells, while Pemphredonini never have more than two submarginal cells in their forewing. More recent classifications treat Psenidae (including Odontosphecini) as a separate family, and sister to the newly-erected family Ammoplanidae, while Pemphredonidae (excluding Ammoplanina) is sister taxon to the Philanthidae.[2]

Fossils

Two fossilized wasps from the Weald Clay, Archisphex and Angarosphex are considered to possibly be in the Pemphredoninae.[4]
