The North American species of the broad-nosed weevil genus Pachyrhinus Schnherr 1823 (Coleoptera: Curculionidae, Entiminae) are revised. Three species of Pachyrhinus are here recognized in North America: P. elegans (Couper 1865), P. californicus (Horn 1876), and P. cinereus (Casey 1888). Pachyrhinus lateralis (Casey 1888) and P. miscix (Fall 1901) are here designated as synonyms of P. elegans. Pachyrhinus crassicornis (Casey 1888) and P. albidus (Fall 1901) are here designated synonyms of P. cinereus (Casey 1888) The previously proposed synonymy of P. ferrugineus (Casey 1888) with P. californicus was confirmed. This revision includes detailed images of diagnostic characters as well as scanning electron micrographs of scale morphology for all species. A key to the Nearctic species of Pachyrhinus is provided. All Nearctic species of Pachyrhinus are considered minor pests of Pinus spp. [Pinaceae].
修订了北美宽鼻象鼻虫属 Pachyrhinus Schnherr 1823 （鞘翅目：象甲科，象鼻虫亚科）的北美种。在北美的三种 Pachyrhinus 得到了认可：P. elegans （Couper 1865），P. californicus （Horn 1876）和 P. cinereus （Casey 1888）。Pachyrhinus lateralis （Casey 1888）和 P. miscix （Fall 1901）被指定为 P. elegans 的同义词。Pachyrhinus crassicornis （Casey 1888）和 P. albidus （Fall 1901）被指定为 P. cinereus （Casey 1888）的同义词。先前提出的 P. ferrugineus （Casey 1888）与 P. californicus 的同义词关系得到了确认。本修订包括所有物种的鉴别特征的详细图像以及鳞片形态的扫描电子显微镜图像。提供了一个北美 Pachyrhinus 种的关键。所有北美的 Pachyrhinus 种都被认为是松属植物的次要害虫[松科]。
