膜翅目昆虫的系统发育位置，特别是蜂科之间的亲缘关系尚未得到解决，还需要进一步的研究。化石记录有助于阐明这一群体的进化史。在本文中，xoanon？Eocenicus sp.11月是始新世Fossillagerstätte Grube Messel(德国)的新描述。尽管该化石的翼脉的一些特征与现存的xxanon属相似，但对于该属的位置仍有一些疑问。在法国古近纪Fossillagerstätte Menat发现一新化石，归属于Urocerus ligniticus(Piton，1940)，并提供了更多关于该物种的形态信息。对严格意义上的剑鱼科化石记录进行了综述，并对不同化石的认识状况进行了综述。
The phylogenetic placement of siricid hymenopterans and especially the relationships among Siricidae are not resolved, and are in need of further investigation. The fossil record helps to illuminate the evolutionary history of this group. In this paper, Xoanon? eocenicus sp. nov. is newly described from the Eocene Fossillagerstätte Grube Messel (Germany). Although several characters of the wing venation of this fossil are similar to the extant genus Xoanon, there remain some doubts concerning the generic placement. A newly found fossil is attributed to Urocerus ligniticus (Piton, 1940) from the Paloecene Fossillagerstätte Menat (France) and provides more morphological information on this species. An overview of the fossil record of Siricidae in the strict sense is given and the state of knowledge on the different fossils is reviewed.
