The Ichneumonidae, also known as ichneumon wasps, ichneumonid wasps, ichneumonids, or Darwin wasps, are a family of parasitoid wasps of the insect order Hymenoptera. They are one of the most diverse groups within the Hymenoptera with roughly 25,000 species described as of 2016. However, this likely represents less than a quarter of their true richness as reliable estimates are lacking, along with much of the most basic knowledge about their ecology, distribution, and evolution. It is estimated that there are more species in this family than there are species of birds and mammals combined. 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.
Pimplinae are a worldwide subfamily of the parasitic wasp family Ichneumonidae.
Acaenitinae is a subfamily of the parasitoid wasp family Ichneumonidae. Female Acaenitinae have a large triangular projecting genital plate.
Lusius is a genus of parasitoid wasps in the tribe Phaeogenini Förster, 1869 or Alomyini Förster, 1869, first described by Pierre Jules Tosquinet in 1903, published after his death. The genus is similar in appearance to species in the genus Heterischnus. Lusius occurs in the Oriental, Afrotropical, Neotropical and Australasian biogeographical regions.
Lusius flummox is a parasitoid wasp found in Uganda and possibly Nigeria. The species is similar in appearance to Lusius tenuissimus, and the precise relationship between the species has yet to be determined. The etymology of the specific name is the word "flummox", in reference to the difficulty of assigning this species to a genus. It was first described by Pascal Rousse and Simon van Noort in 2013.
Trogus is a genus of parasitoid wasp found in the Holarctic and Neotropic regions. It is placed in the subfamily Ichneumoninae and the tribe Ichneumonini. Trogus species are parasites of larvae and pupae of the swallowtail butterfly family, Papilionidae. The genus consists of twelve extant and one extinct species.
Rhyssinae is a subfamily of parasitoid wasps in the family Ichneumonidae. It contains eight genera and 259 described species, but there are likely many undiscovered species.
Aoplus is a genus of insects belonging to the family Ichneumonidae.
Diphyus is a genus of parasitoid wasps belonging to the family Ichneumonidae.

Platylabini is a tribe of ichneumon wasps in the family Ichneumonidae. There are at least 40 genera and about 8 described species in Platylabini.
Joppa is a genus of Neotropical parasitoid wasps in the family Ichneumonidae.
Listrodromus nycthemerus, the holly blue Darwin wasp, is a species of ichneumon wasp belonging to the family Ichneumonidae. This species is a parasitoid, its sole host species being the holly blue butterfly.
Listrodromus is a genus of ichneumon wasps belonging to the family Ichneumonidae. These wasps are parasitoids of butterflies of the family Lycaenidae, laying eggs in the caterpillars.
