Abstract

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. emarginatussp. nov. and P. truncatussp. 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.
