Spathiopterygidae

Spathiopterygidae is an extinct family of small parasitic wasps, known from the Cretaceous (Barremian to Santonian) of Laurasia and Northern Gondwana. They are suggested to be members of Diaprioidea, in part due to their similarly reduced wing venation. Some members of the group reduced or lost the hindwings entirely.
