Taxonomic Review of Eumenes Latreille, 1802 (Hymenoptera, Vespidae, Eumeninae) from the New World

Abstract

The genus Eumenes Latreille, 1802, from the New World, is revised based on external morphology and male genitalia. New synonymy is proposed as follows: E. aureus Isely, 1917 = E. americanus de Saussure, 1852; E. bollii oregonensis Bequaert, 1838, and E. b. ehrenbergi Zavattari, 1912 = E. bollii Cresson, 1872; E. consobrinus pedalis Fox, 1894 = E. consobrinus de Saussure, 1855; E. crucifera bolliformis Viereck, 1908, E. c. nearcticus de Saussure, 1855 and E. c. stricklandi Bequaert, 1944 = E. crucifera Provancher, 1888; E. smithii belfragei Cresson, 1872 = E. smithii de Saussure, 1852; E. verticalis coloradensis Cresson, 1875, E. v. neoboreus Bequaert, 1944, E. v. tricinctus Isely, 1917 = E. verticalis Say, 1824. Eumenes flavitinctus Bohart, 1950, revised status, is no longer a subspecies of E. crucifera but elevated to specific level. Eumenes brunneus is elevated to the specific level and a new name is proposed because of homonymy, E. bequaerti Grandinete & Carpenter nom. nov. An identification key for all the species of the genus from the New World is provided and the geographical distributions are updated.
