Panguidae is an extinct family of aculeate wasps. It has two unambiguous members, Protopangu known from the Early Cretaceous (early Barremian) amber from the Wessex Formation of southern England[1] and Pangu from the mid-Cretaceous (latest Albian-earliest Cenomanian) Burmese amber of Myanmar.[2] The genus Prosphex, originally considered incertae sedis, was suggested to be a member of the family in a later publication. Their relationships with other aculates are uncertain, and they are considered to be the only members of the superfamily Panguoidea.[3][2] A specimen of Prosphex was observed with a substantial amount of angiosperm pollen near and within its mouth, implying that it was pollenivorous, and acted as a pollinator for flowering plants.[4] However, other later publications have placed Prosphex outside of Panguidae.[5]
