Spathiopterygidae Explained

Spathiopterygidae is an extinct family of small parasitic wasps, known from the Cretaceous (Barremian to Santonian) of Laurasia and Northern Gondwana.^{[1] [2]} 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.
