Chihuahuanus
Chihuahuanus is a genus of scorpions in the family Vaejovidae, established in 2013 and endemic to northern Mexico. The genus comprises medium-sized scorpions that are not considered medically important to humans. Two described species, C. coahuilae and C. crassimanus, have been characterized for venom composition, revealing toxic fractions with lethal effects in mammals and insects and antimicrobial activity against bacterial pathogens.
Cotinis impia
Cotinis impia is a scarab beetle in the genus Cotinis, first described by Fall in 1905. The species is known from the southwestern United States and northwestern Mexico. Field observations indicate it has been collected on Baccharis sarothroides (desert broom), though additional host associations remain poorly documented. Like other members of the genus Cotinis, it belongs to the flower chafer group within Scarabaeidae.
Diplotaxis abnormis
Diplotaxis abnormis is a small scarab beetle in the family Scarabaeidae, subfamily Melolonthinae. The species was described by Fall in 1909 and belongs to the tribe Diplotaxini. It is distributed in the southwestern United States (Arizona, New Mexico) and northern Mexico (Chihuahua, Sonora). Like other members of the genus Diplotaxis, it is likely a nocturnal species that congregates on vegetation to detect pheromone trails for mate location.
Diplotaxis brachyptera
A small scarab beetle in the genus Diplotaxis, family Scarabaeidae, described by Patricia Vaurie in 1960. The species name 'brachyptera' (short-winged) suggests reduced flight capability. Records indicate presence in arid and semi-arid regions of the southwestern United States and northern Mexico. Like other Diplotaxis species, adults are likely nocturnal and may aggregate on vegetation.
Epiphragma arizonense
Epiphragma arizonense is a crane fly species described by Alexander in 1946. The species is known from the southwestern United States and northwestern Mexico. Like other members of the genus Epiphragma, it is distinguished by distinctive wing patterning and male genitalia morphology. The male was redescribed and illustrated in a 2012 taxonomic review of North American Epiphragma species.
Hadoa chisosensis
Southern Piñon Sun-Singer
Hadoa chisosensis is a species of annual cicada in the genus Hadoa, native to Texas and adjacent areas of northern Mexico. The species is commonly known as the Southern Piñon Sun-Singer. As a member of the Cicadidae family, it produces acoustic signals typical of cicadas. The specific epithet 'chisosensis' refers to the Chisos Mountains region of Texas, indicating its association with this geographic area.
Hemileuca oliviae
Range Caterpillar, Range Caterpillar Moth
Hemileuca oliviae, the range caterpillar, is a day-flying saturniid moth native to grasslands of the southwestern United States and northern Mexico. The species is notable for periodic population outbreaks that can cause significant damage to rangeland vegetation, impacting forage availability for livestock. Its distribution is restricted to open grassland habitats due to predation pressure from woodland rodents on eggs and pupae. The moth has been studied extensively for its ecological interactions, including host plant relationships, water physiology, and natural enemy complexes.

Listrochelus huachuca is a scarab beetle species in the family Scarabaeidae, subfamily Melolonthinae, described by Saylor in 1940. The species is named for the Huachuca Mountains of southeastern Arizona, where it has been collected. It belongs to a genus of rhizotrogine scarabs whose larvae typically develop in soil and feed on plant roots.
Omorgus inflatus
Omorgus inflatus is a species of hide beetle in the family Trogidae, described by Loomis in 1922. Members of this genus are commonly known as skin beetles and are associated with decomposing animal matter. The species has been recorded from the southwestern United States and northern Mexico.
Phyllophaga sonora
Phyllophaga sonora is a species of scarab beetle described by Saylor in 1939. It belongs to the genus Phyllophaga, a large group commonly known as May beetles or June bugs. The species has been documented in the southwestern United States and northwestern Mexico. Like other members of its genus, it is presumed to have subterranean larval stages and adult emergence patterns tied to seasonal rainfall, though specific biological details remain poorly documented.
