Abstract
The fossil Embolemidae (Hymenoptera: Chrysidoidea) are reviewed. Keys to the genera and species of
this family are presented. Five new species of Embolemus are described from Cenomanian Kachin amber
(Myanmar), namely: Em. antiquus sp. nov., Em. burmensis sp. nov., Em. cretacicus sp. nov., Em. ohmkuhnlei
sp. nov. and Em. zherikhini sp. nov. They are the first Embolemus species recorded from Burmese amber.
One new species of Embolemopsis from Barremian Wealden amber (UK), is described: Ep. maryannae sp.
nov., the oldest known embolemid wasp and the first hymenopteran described fromWealden amber. The
genus Ponomarenkoa is transferred from Dryinidae to Embolemidae. A new species of Ponomarenkoa
(P. burmensis sp. nov.) is described from Cenomanian Kachin amber. The genera of Embolemidae are
divided into three groups. The phylogenetic significance of the new species of Embolemidae and the
history of the family are discussed. Nymphs of Cixiidae and Achilidae are recorded as hosts of Embolemidae.
Possible hosts of fossil embolemids are discussed. For the first time, Achilidae (Protepiptera
kaweckii, from Baltic amber) are recorded as hosts of Dryinidae. Protepiptera kaweckii is also recorded for
the first time from Rovno amber.
