Holcotetrastichus is a genus of hymenopteran insects of the family Eulophidae. As larvae, they are parasitoids of Cassida beetles. [1]
The Eulophidae is a large family of hymenopteran insects, with over 4,300 described species in some 300 genera. The family includes the genus Elasmus, which used to be treated as a separate family, "Elasmidae", and is now treated as a subfamily of Eulophidae. These minute insects are challenging to study, as they deteriorate rapidly after death unless extreme care is taken, making identification of most museum specimens difficult. The larvae of very few species feed on plants, but the majority are primary parasitoids on a huge range of arthropods at all stages of development. They are exceptional in that they are one of two hymenopteran families with some species that are known to parasitize thrips. Eulophids are found throughout the world in virtually all habitats.
Aprostoporoides is a small Indomalayan genus of hymenopteran insects of the family Eulophidae which was described in 2004 with two newly described species from Kerala.
Asecodes is a genus of hymenopteran insects of the family Eulophidae. They are endoparasitoids of Galerucella larvae.
Baeoentedon is a genus of hymenopteran insects of the family Eulophidae, they are parasitoids of whitefly from the family Aleyrodidae which are found on trees of the genus Ficus. They have been recorded from Australia, China, India, Indonesia and Florida. A fifth species, Baeoentodon farazi, was described from Karnataka, India, in 2017.
Chouioia is a genus of endoparasitic wasp of the family Eulophidae. Chouioia cunea is considered an important parasite of the fall webworm in China, where the moth is an invasive species.
Chrysocharis is a genus of hymenopteran insects of the family Eulophidae. Species in this genus are parasitoids as larvae, with hosts of multiple species being Agromyzidae flies.
Colpoclypeus is a genus of hymenopteran insects of the family Eulophidae.
Emersonella is a genus of hymenopteran insects of the family Eulophidae. Several species are known to be phoretic parasitoids of female tortoise beetles, laying their eggs in the eggs of the beetle host.
Eprhopalotus is a genus of hymenopteran insects of the family Eulophidae. Their distribution varies between species but ranges from Costa Rica, Mexico to Texas. There are currently 5 species of Eprhopalotus:
Euplectrus is a genus of hymenopteran insects of the family Eulophidae.
Goetheana is a genus of hymenopteran insects of the family Eulophidae. As a parasitoid of thrips, this wasp is used in biological pest control.
Horismenus is a genus of hymenopteran insects of the family Eulophidae occurring primarily in the Americas. As of 2015 over 400 species in the genus have been described. Horismenus species are often described as parasitizing other insects.
Leptocybe invasa, the blue gum chalcid wasp or eucalyptus gall wasp, is a chalcid wasp which is the only species in the monotypic genus Leptocybe in the subfamily Tetrastichinae, of the family Eulophidae. It is a gall wasp which causes the formation of galls on a number of species of Eucalyptus, it was described in 2004 after galls were found in river red gums in the Mediterranean and Middle East and has since been found to be a widespread species where its host trees are planted. It is indigenous to Australia.
Melittobia is a genus of hymenopteran insects of the family Eulophidae.
Notanisomorphella is a genus of hymenopteran insects of the family Eulophidae. They are parasitoids with hosts including Coleophoridae, leaf mining beetles, and spider eggs.
Omphale is a genus of hymenopteran insects of the family Eulophidae. It has cosmopolitan distribution.
Parzaommomyia is a genus of hymenopteran insects of the family Eulophidae.
Pnigalio is a genus of hymenopteran insects of the family Eulophidae. Nearly 100 species have been described of which about half may be valid. All species are parasites of other insects. Their biology varies widely among those species that have been studied. Some are ectoparasites, others parasitoid, and still others are hyperparasitoids and their hosts include beetles, flies, hymenopteran and lepidopterans.
Quadrastichus is a genus of hymenopteran insects of the family Eulophidae.
Tetrastichinae is a subfamily of the chalcid wasp family Eulophidae. It is one of the largest subfamilies of the Eulophidae containing over 100 genera and nearly 3,000 species. The species of the family Tetrastichinae are found in almost any type of terrestrial habitat and have a worldwide distribution, except Antarctica. They show a varied biology and hosts for Tetrastichinae wasps have been identified from over 100 different insect families, across 10 different orders and they have also been recorded as being parasitoids on nematodes, mites and spiders' eggs. Some species are even phytophagous, while others are inquilines and yet others are gall formers.
