Abstract
The genus Oropodes is characterized and revised with 18 species being treated. Members of this genus are found in temperate forests to desert brush lands from Oregon to Baja California, but are associated primarily with dry forests and shrub lands of California. Keys to males and females, where known, are provided. Seven species are redescribed: Oropodes arcaps (California), Oropodes dybasi (Oregon), Oropodes ishii (California), Oropodes nuclere (California), Oropodes orbiceps (California), Oropodes rumseyensis (California), Oropodes yollabolly (California). The name Oropodes raffrayi (California) is raised from synonymy and the species is redescribed, NEW STATUS. Ten new species are described: Oropodes aalbui (California), Oropodes bellorum (California), Oropodes casson (California), Oropodes chumash (California), Oropodes esselen (California), Oropodes hardyi (California), Oropodes serrano (California), Oropodes tataviam (California), Oropodes tongva (California), and Oropodes tipai (Baja California, Mexico), NEW SPECIES. These species are placed into three species groups: the arcaps-group, the orbiceps-group, and the raffrayi-group. Data for a new record of Euplecterga fideli are given, and a list of the unassociated Oropodes females with distinctive genitalia is included with their label data.
