Diplolepididae is a family of small gall-inducing wasps.

Until recently these wasps were included in the gall wasp family (Cynipidae) but were moved to their own family based on genetic and morphological features.

[2] Diplolepidinae includes about 60 species in two genera (Diplolepis and Liebelia), all of which induce galls on roses in which the larvae live and feed.

[2] Pediaspidinae is composed of two monotypic genera: Himalocynips and Pediaspis.

[2] The biology of this subfamily is poorly known, though Pediaspis aceris induces galls on a species of maple.
