African Arthropods/Afrotropical Encyrtidae Key

Encyrtidae is a large family of parasitic wasps in the Superfamily Chalcidoidea. There are more than 640 described species of Afrotropical Encyrtidae in about 130 genera. Many encyrtid species are parasitoids of scale insects, some of which are pests that reduce the productivity of agricultural crops across the world.

=Key to the genera of Afrotropical Encyrtidae= This key is based on this paper: Prinsloo, G. L., & Annecke, D. P. (1979). A key to the genera of Encyrtidae from the Ethiopian region, with descriptions of three new genera (Hymenoptera: Chalcidoidea). Journal of the Entomological Society of southern Africa, 42(2), 349-382. The Universal Chalcidoidea Database, WaspWeb , and other on-line sources were used to add details.

1 Encyrtidae
Diagnostic features of Encyrtidae include: mesopleuron very enlarged; mid coxae level with middle of mesopleuron in side view; cercal plates advanced; linea calva distinct; mesoscutum transverse and without distinct notauli. There are illustrations of these features on another page of the African Arthropods project.
