The genus Elasmus is the only member of the hymenopteran subfamily Elasminae, and contains over 200 species worldwide. They are mostly parasitoids or hyperparasitoids of lepidopteran larvae, though several species are parasitoids of Polistes paper wasp larvae. Some authorities now place Elasmus in the subfamily Eulophinae.

Ophelimus maskelli is a species of chalcid wasp about 1mm long, known as the eucalyptus gall wasp, found in Australia, Mediterranean Region, and the Middle East. It is considered a plant pest as females lay eggs on immature eucalyptus leaves; the larvae produce galls on the leaves. Heavy infestations induce much galling which causes widespread defoliation and loss of growth. Wasps may emerge in large numbers in the spring, forming clouds which are a nuisance to humans.

Pediobius is a genus of hymenopteran insects of the chalcid wasp family Eulophidae. Like their relatives, the larvae of these diminutive wasps are parasitoids of various arthropods. Some Pediobius are used in biological pest control.
