The Ichneumonidae, also known as the ichneumon wasps, Darwin wasps, or ichneumonids, is a parasitoid wasp family within the insect order Hymenoptera. This insect family is among the most species-rich branches of the tree of life. At the same time, it is one of the groups for which our knowledge most severely lags behind their actual diversity. The roughly 25,000 species described today probably represent less than a quarter of their true richness, but reliable estimates are lacking, as is much of the most basic knowledge about their ecology, distribution and evolution. Ichneumonid wasps, with very few exceptions, attack the immature stages of holometabolous insects and spiders, eventually killing their hosts. They thus fulfill an important role as regulators of insect populations, both in natural and semi-natural systems, making them promising agents for biological control.
Campopleginae is a large subfamily of the parasitoid wasp family Ichneumonidae with a world-wide distribution. Species in this subfamily have been used in the biological control of the alfalfa weevil, clover weevil, various species of Heliothis, oriental army worm, European corn borer, larch sawfly, and others.
Tersilochinae is a worldwide subfamily of the parasitic wasp family Ichneumonidae.
Tersilochus is a genus of the parasitic wasp family Ichneumonidae. The type species is Tersilochus jocator.

Diadegma meliloti is a wasp first described by Horstmann in 1973. It is a member of the genus Diadegma and family Ichneumonidae. No subspecies are listed.
Diadegma auricellae is a wasp first described by Horstmann in 2008. No subspecies are listed.

Anomalon is a large genus of parasitoid wasps belonging to the family Ichneumonidae. This may be the only genus in the tribe Anomalonini, although Neogreeneia Viereck, 1912 is sometimes considered a valid genus of the tribe.
Anomalon cruentatum is a species of parasitoid wasps belonging to the family Ichneumonidae.
Trogus is a genus of parasitoid wasp found in the Holarctic and Neotropic regions. It is placed in the subfamily Ichneumoninae. Trogus species are parasites of larvae and pupae of the swallowtail butterfly family, Papilionidae. The genus consists of twelve extant and one extinct species.
Probles is a genus of ichneumonid wasp of the subfamily Tersilochinae. It has a widespread distribution.
Ferdinand Rudow was a German entomologist best known for the poor quality of his taxonomic work. He described over 200 species of wasps during his lifetime, almost all of which have been revised as synonyms of other species.
Clypeoplex is a genus of parasitoid wasps belonging to the family Ichneumonidae.
Dolophron is a genus of parasitoid wasps belonging to the family Ichneumonidae.
Porizon is a genus of parasitoid wasps belonging to the family Ichneumonidae.
Arotrephes is a genus of parasitoid wasps belonging to the family Ichneumonidae.
