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.[1][2] It contains two subfamilies: Diplolepidinae and Pediaspidinae.[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][3][4] This subfamily was formerly included in Cynipidae as the tribe Diplolepidini.[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.[2] This subfamily was formerly included in Cynipidae as the tribe Pediaspini.[2]
