Article: First records of fossil tremecine hymenopterans
Two Hymenoptera, from the Upper Oligocene of Enspel (Germany) and the Upper Pliocene of Willershausen (Germany), are described and their systematic position is discussed. The fossil from Enspel shows parts of the body and almost the complete wing venation. After analysis of the phylogeny of Tremecinae (Siricidae) it could be placed near Eriotremex and Afrotremex. The specimen from Willershausen has only the apical part of one forewing preserved and belongs to Tremex.
