Agrilus malvastri
Agrilus malvastri is a metallic wood-boring beetle in the family Buprestidae, described by Fisher in 1928. It is one of the few North American Agrilus species documented as routinely visiting flowers, specifically those of Sphaeralcea (globemallows). The species occurs in Central America and North America, with records from the southwestern United States including New Mexico, Utah, and Arizona. Unlike most Agrilus species, which are associated with woody plants, A. malvastri appears to be associated with herbaceous plants in the family Malvaceae.
Dellacasiellus ruficlarus
Dellacasiellus ruficlarus is a species of dung beetle in the subfamily Aphodiinae, originally described by Fall in 1932. It belongs to a small genus of aphodiine scarabs distributed across western North America. The species has been documented in arid and semi-arid regions from Canada to Mexico.
Dieunomia nevadensis arizonensis
Arizona Nomia
Dieunomia nevadensis arizonensis, known as the Arizona Nomia, is a subspecies of sweat bee in the family Halictidae. It is a ground-nesting bee distributed across the southwestern United States and adjacent regions of Mexico. The subspecies was first described by Cockerell in 1899 and is distinguished from the nominate subspecies by geographic range and subtle morphological differences. Like other members of the genus Dieunomia, it is a specialist pollinator associated with particular host plants.
Eudesmia arida
Arid Eudesmia Moth
Eudesmia arida is a small moth in the family Erebidae, first described by Skinner in 1906. It occurs in the southwestern United States and Mexico, where adults are active during summer and early autumn. The species has a wingspan of 23–30 mm.
Idiostatus hermannii
Idiostatus hermannii is a species of katydid in the family Tettigoniidae, originally described as Steiroxys hermannii by Thomas in 1875. It belongs to a genus of North American katydids characterized by relatively short wings and male genitalia with distinctive morphological features. The species has been recorded across the western United States, particularly in arid and semi-arid regions.
Pandeleteius rotundicollis
Pandeleteius rotundicollis is a species of broad-nosed weevil described by Fall in 1907. It belongs to the family Curculionidae, one of the largest families of beetles. The species is known from scattered localities in southwestern North America, with records from Texas, New Mexico, Arizona, and the Mexican state of Chihuahua. Like other members of its genus, it likely inhabits arid and semi-arid environments, though specific ecological details remain poorly documented.
Protogygia biclavis
Protogygia biclavis is a noctuid moth described by Grote in 1879. It is strongly associated with gypsum dune habitats, particularly the White Sands National Monument in New Mexico, and has been recorded from additional arid regions in California, Utah, and Arizona. The species exhibits local adaptation to white gypsum sand environments.
Pseudonomoneura
Pseudonomoneura is a genus of mydas flies (family Mydidae) comprising seven described species distributed in western North America, particularly in arid and semi-arid regions of the southwestern United States and northwestern Mexico. The genus was established by Bequaert in 1961 to accommodate species previously placed in related genera. Adults are generally robust, moderately sized flies with distinctive wing venation characteristic of the family.
