Aphelinus Dalman 1820
The species of this genus are endoparasitoids of aphids and several have been used as biological control agents (e.g. Aphelinus mali against Eriosoma lanigerum). The genus contains more than 90 species and has a world-wide distribution.
The wasps are usually minute, < 1.5 mm, and dark brown to yellow. The genus is closely related to the genus Aphytis and both genera differ in relatively few morphological characters like the structure of the antennae (e.g. with 6 segments in Aphelinus but only 5 in Aphytis).
