Discovery and description of the first known fossil Signiphoridae (Hymenoptera, Chalcidoidea)

Abstract

Chartocerus azizae sp. nov. is described as the first known fossil from the family Signiphoridae, based on two inclusions in the same piece of Eocene Baltic amber (36.7–48.5 million years ago). Implications of the morphology of C. azizae are discussed, indicating that it should be placed in Chartocerus.
