A revision of the North American genus Proctorus (Coleoptera, Curculionidae, Ellescini) with descriptions of two new species

Collection: Pensoft Publishers

Keywords: Museology · Topics: Forest Insect Ecology and Management, Coleoptera Taxonomy and Distribution, Hymenoptera taxonomy and phylogeny

The rarely collected North American endemic genus Proctorus (Coleoptera, Curculionidae, Ellescini) has hitherto contained two described species, P. armatus LeConte, 1876 and P. decipiens (LeConte, 1876). Here, Proctorus is revised and two new species, namely P. emarginatus sp. nov. and P. truncatus sp. nov., are described. Lectotypes for P. armatus and P. decipiens are designated from known syntypes. All four species in the genus are associated with Salicaceae, but, in addition to differences in external and genital morphology, there is also evidence of differing host plant usage between the species. A photographic key to the four species is provided to facilitate identification.
