Review of Nearctic Aulogymnus (Hymenoptera: Eulophidae) with nomenclatural changes

摘要

The taxonomy of the Nearctic species of Aulogymnus Forster, 1851 (Hymenoptera: Eulophidae) is revised. Five new species of Aulogymnus are described and illustrated: A. bouceki.^p. nov., A. gorditus sp. nov., A. purpurescens sp. nov., A. smithi sp. nov., and A. virginiensissp. nov. Lectotypes are designated for A. flavimaculata Girault, 1916, A. flavitibiae Girault, 1916, A. io Girault, 1916, and A. marilandia. Aulogymnus marilandia Girault, 1917 is synonymized with A. io. Most host record^ reflect a specialization by Aulogymnus spp. on gall wasps (Hymenoptera: Cynipidae), which form galls on various oaks (Fagaceae: Quercus spp.). A key to Nearctic species is given and host use is summarized.
