Abstract

A new fossil horntail wood wasp (Hymenoptera, Symphyta, Siricidae), Eourocerus anguliterreus gen. et sp. nov. from an early Eocene Okanagan Highlands locality at Republic, Washington, USA is described. Its forewing is most like that of the extant and fossil genus Urocerus Geoffroy, 1785. It is the third fossil siricid described from North America. We treat Xeris dorbnikensis Manukyan Smirnova, 2021 and Xeris sp. of Manukyan Smirnova (2021) as Urocerus dorbnikensis (Manukyan Smirnova, 2021), comb. nov. and Urocerus sp., both tentatively belonging to the genus, Urocerus klebsi Brues, 1926 as Xeris klebsi (Brues, 1926) comb. nov., and Afrotremex or Eriotremex sp. of Wedmann (1998) as a species of Eriotremex Benson, 1943. A key to extant and extinct genera of Siricinae by forewing characters is given.

摘要

一种新的化石角木蜂科（膜翅目，缨尾目，木蜂科），Eourocerus anguliterreus gen. et sp. nov. 来自美国华盛顿州共和市的早始新世奥卡诺根高地的一个地点。它的前翅与现存和化石属 Urocerus Geoffroy，1785 最为相似。它是北美描述的第三种化石木蜂科。我们将 Xeris dorbnikensis Manukyan Smirnova，2021 和 Xeris sp. of Manukyan Smirnova（2021）视为 Urocerus dorbnikensis（Manukyan Smirnova，2021），组合。新，暂定属于 Urocerus klebsi Brues，1926 的属，Xeris klebsi（Brues，1926）组合。新，和 Afrotremex 或 Eriotremex sp. of Wedmann（1998）是 Eriotremex Benson，1943 的一个种。给出了根据前翅特征对现存和已灭绝的木蜂科属的关键。
