Abstract
"The genus Pseudopsallus Van Duzee is revised and proposed as the senior synonym of Bifidungulus Knight and Hesperocapsus Knight. Twenty species are recognized including six that are new: Pseudopsallus lajuntae, Pseudopsallus enceliae, Pseudopsallus lattini, Pseudopsallus mojaviensis, Pseudopsallus occidentalis, and Pseudopsallus presidio. The following taxa, listed by the most recently recognized combination, are transferred to Pseudopsallus: Bifidungulus puberus (Uhler), Bifidungulus viridicans Knight, Hesperocapsus abroniae (Knight), Hesperocapsus anograe (Knight), Hesperocapsus artemisicola (Knight), Hesperocapsus atriseta (Van Duzee), Hesperocapsus demensus (Van Duzee), Hesperocapsus hixsoni Knight, Hesperocapsus major Knight, Hesperocapsus plagiatus Knight, Hesperocapsus sericatus (Uhler), and Hesperocapsus stitti Knight. Oncotylus repertus Uhler is reinstated as a valid species, removed from synonymy with Hesperocapsus sericatus (Uhler), and transferred to Pseudopsallus. The following new synonymies are proposed: Pseudopsallus atriseta (Van Duzee) = Hesperocapsus tanneri (Knight) and Hesperocapsus nigricornis Knight; Pseudopsallus demensus (Van Duzee) = Pseudopsallus nicholi Knight and Hesperocapsus gaurae Knight; Pseudopsallus repertus (Uhler) = Hesperocapsus davisi (Knight) and Hesperocapsus utahensis Knight; Pseudopsallus stitti (Knight) = Hesperocapsus tinctus Knight. Lectotypes are designated for: Macrotylus angularis Uhler, Oncotylus puberus Uhler, and Oncotylus sericatus Uhler. Illustrations are provided for the male genitalic structures of all species, and scanning electron micrographs are presented for the pretarsus and scale-like setae of representative species. A revised diagnosis and description of Pseudopsallus are included. A key to all currently recognized species is given, as well as a detailed diagnosis and a description of the male genitalia for each species, and descriptions of all new species. A phylogenetic analysis of the species is presented, using a species in a new genus from Mexico for outgroup comparison. The resulting species classification recognized three species groups. The male genitalia, fine structure of the scale-like setae, and pretarsus of several genera of Orthotylini are surveyed to evaluate the utility of these structures as phylogenetic character systems. Distribution maps are provided for all species, indicating a range for Pseudopsallus from the Prairie Provinces of Canada south to the central plateau region of Mexico and west to California. Members of the genus occur primarily on herbaceous plants belonging to the families Nyctaginaceae (e.g., Abronia Juss.) and Onagraceae (e.g., Gaura L., Oenothera L.), and on Artemisia L. (Asteraceae)"--P. [1]-2.
