Notes on Polyphylia Harris with a description of a new species (Coleoptera: Scarabaeidae: Melolonthinae)

Polyphylla aeolus La Rue, new species, is described from the Kelso Sand Dunes, Mojave Desert, San Bernardino County, California, U.S.A. Illustrations of dorsal habitus, significant morphological details, and adult genitalic forms are provided. A description of the type locality including geographical and ecological parameters is presented. Taxonomic problems within the genus and limitations of recently proposed methods of species identification are discussed. A modified key is provided to distinguish the new species. The heretofore undescribed females of Polyphylla anteronivea Hardy, P. mescalerensis Young, P. nubila Van Dyke, and P. pottsorum Hardy, are described. The larval host of P. erratica Hardy is reported, and the adult female is redescribed from pristine specimens. A dorsal habitus illustration of each female is provided. Bionomic and distributional data are presented for Polyphylla avittata Hardy, P. cavifrons LeConte, P. hirsuta Van Dyke, P. monahansensisHardy, P. petiti Guerin, P. stellata Young, andP. squamiventris Cazier

Natural history, ecology, and conservation of the genus \u3ci\u3ePolyphylla\u3c/i\u3e Harris, 1841. 1. New species from the southwestern United States and Baja California, Mexico, with notes on distribution and synonymy (Coleoptera: Scarabaeidae: Melolonthinae)

Four new species of the genus Polyphylla Harris (Coleoptera: Scarabaeidae: Melolonthinae) from the southwestern United States and Baja California, Mexico, are described and illustrated: Polyphylla anivallis, P. koso, P. morroensis, and P. socorriana. Two nomenclatural changes are proposed: Polyphylla ratcliffei Young is placed into synonymy with P. avittata Hardy and Andrews, new synonymy; P. uteana Tanner is removed from synonymy and reinstated as a valid species, reinstated status. The females of P. monahansensis Hardy and Andrews and P. stellata Young are described and illustrated. New distributional records and ecological associations are amended for P. avittata Hardy and Andrews, P. cavifrons LeConte, P. concurrens Casey, P. crinita LeConte, P. diffracta Casey, P. mescalerensis Young, P. petitii (Guérin-Méneville), and P. rugosipennis Casey. A checklist of the “Western Clade” species of Polyphylla, north of Mexico, is included. Cuatro especies nuevas del género Polyphylla Harris (Coleoptera: Scarabaeidae: Melolonthinae) del suroeste de los Estados Unidos y Baja California, México, se describen e ilustran: Polyphylla anivallis, P. koso, P. morroensis, y P. socorriana. Se proponen dos cambios de nomenclatura: Polyphylla ratcliffei Young se coloca en sinonimia con P. avittata Hardy y Andrews, nueva sinonimia; P. uteana Tanner es removido de la sinonimia y reinstalado como una especie válida, estado reinstalado. Las hembras de P. monahansensis Hardy y Andrews y P. stellata Young se describen e ilustran. Nuevos registros de distribución y asociaciones ecológicas se complementan para P. avittata Hardy y Andrews, P. cavifrons LeConte, P. concurrens Casey, P. crinita LeConte, P. diffracta Casey, P. mescalerensis Young, P. petitii (Guérin-Méneville), y P. rugosipennis Casey. Se incluye una lista de las especies del “Clado Occidental” de Polyphylla, al norte de México
