Charipidae

Definition

A family of minute parasitoid wasps in the order Hymenoptera, characterized by reduced wing venation, compact bodies, and association with aphidophagous predators as hosts. Members are hyperparasitoids, typically attacking the primary parasitoids of aphids such as Aphidiinae (Braconidae) or Aphelinidae, thereby occupying the fourth trophic level in food webs. Adults are often collected by Malaise trapping or water pan trapping and are recognized by their distinctive wing shape with a pterostigma and few closed cells.

Etymology

From Greek charis (grace, beauty) + Latin -idae (family suffix), referring to the delicate appearance of these small wasps.

Example

Charipinae (formerly treated as a subfamily within Figitidae, now elevated to family rank as Charipidae) includes genera such as Alloxysta and Phaenoglyphis, which emerge from mummified aphids containing the remains of both the aphid host and its primary parasitoid wasp.

Synonyms

• Charipinae (former rank)

Related Terms

• Figitidae
• Cynipoidea
• hyperparasitoid
• aphid mummy
• Aphidiinae
• trophic cascade
• secondary parasitoid

Usage Notes

Taxonomic rank has been contentious; Charipidae was historically treated as subfamily Charipinae within Figitidae but is now widely accepted as a distinct family within Cynipoidea based on molecular and morphological data. The family contains two subfamilies: Charipinae and Alloxystinae. Identification to genus requires slide-mounting and examination of wing venation and antennal structure. Ecologically significant as indicators of complex parasitoid communities in aphid systems.
