Hymenoptera taxonomy and phylogeny

Abstract Protostephanus ashmeadi Cockerell is confirmed to be a stephanid, and illustrated. The taxonomic status of Protostephanus Cockerell and Electrostephanus Brues, their relationships with extant genera of Stephanidae, and problems in defining or synonymizing fossil genera of the family are discussed. Electrostephanus is provisorily redefined, two fossil species, E. sulcatus sp. n. and E. neovenatus sp. n. are described and illustrated from male specimens preserved in Eocene Baltic amber, and a key to species provided.
