Ceraphronidae

Definition

A small family of minute wasps (Hymenoptera) comprising approximately 14 genera and 360 described species, with many additional species remaining undescribed. Members are predominantly parasitoids, with some species acting as hyperparasitoids, and many are soil-dwelling; a notable proportion of soil-inhabiting species are wingless. The family remains poorly studied compared to other parasitoid wasp groups.

Etymology

From the type genus Ceraphron, derived from Greek keras (horn) and phron (mind or spirit), alluding to the distinctive antennal structure.

Example

Ceraphronidae are frequently encountered in soil extraction samples from agricultural fields, where wingless females parasitize the larvae of other parasitoid wasps, functioning as hyperparasitoids in complex food webs.

Synonyms

• ceraphronid wasps
• ceraphronids

Related Terms

• Hymenoptera
• Parasitoid
• hyperparasitoid
• Megaspilidae
• Ceraphronoidea
• soil fauna
• wingless insect

Usage Notes

Distinguished from the closely related family Megaspilidae, with which Ceraphronidae forms the superfamily Ceraphronoidea. The family's biology is poorly known; most records derive from passive soil sampling rather than direct host observation. Winglessness in females is convergent with other soil-dwelling Hymenoptera and should not be used as a sole diagnostic character.
