New ceraphronoid wasps in Cretaceous and Cenozoic ambers from Lebanon, New Jersey, and India (Hymenoptera: Ceraphronoidea)

New parasitoid wasps of the superfamily Ceraphronoidea are systematically described and figured in various Cretaceous and Cenozoic ambers, ranging in age from Barremian (Early Cretaceous) to Ypresian (early Eocene). A new family, putatively a stem group to Megaspilidae + Ceraphronidae, is described from a single female in Barremian amber from Lebanon. Ceospilidae n. fam., currently including only the type genus and species — Ceospilus phoenicius n. gen., n. sp. — are distinguished from other ceraphronoids. Two new species of Megaspilidae are described: Conostigmus novacaesarea n. sp. from the Turonian amber of New Jersey, USA and Dendrocerus ypresicus n. sp. from the Ypresian amber of Gujarat, India.
