Bryolymnia biformata
Bryolymnia biformata is a small noctuid moth described in 2010 from the sky island mountain ranges of southeastern Arizona. The species is distinguished by two distinct color forms of adults, which inspired its Latin name. It has been documented only from the Huachuca, Patagonia, and Santa Rita Mountains.

Ceratomia sonorensis
Sonoran sphinx
Ceratomia sonorensis, known as the Sonoran sphinx, is a hawkmoth in the family Sphingidae. The species inhabits high-elevation Madrean woodland in Sonora, Mexico and southeastern Arizona. Adults are active during summer months, with larvae feeding on Fraxinus (ash) species. The species was described by Ronald Hodges in 1971.

Chrysina gloriosa
glorious beetle, glorious scarab, Glorious Jewel Scarab
Chrysina gloriosa is a metallic green scarab beetle renowned for its striking iridescent appearance. Adults measure 20–30 mm in length and display bright green elytra with silver longitudinal stripes, though rare red and purple color forms occur. The species inhabits sky island mountain ranges in the southwestern United States and northern Mexico, where adults feed primarily on juniper foliage and larvae develop in decaying wood of Arizona sycamore. Active both diurnally and nocturnally, adults are most frequently encountered from June through August and are strongly attracted to ultraviolet light sources. The beetle's structural coloration arises from cholesteric liquid crystal organization of chitin molecules in the cuticle, producing optical properties that change with light incidence angle.

Drapetes chiricahua
Drapetes chiricahua is a species of fungus weevil in the family Anthribidae, named after the Chiricahua Mountains of southeastern Arizona. The species epithet reflects its type locality in this sky island mountain range, part of the Madrean Archipelago. Like other members of the genus Drapetes, it belongs to a group of beetles associated with fungal substrates. The Chiricahua Mountains are renowned for high endemism due to their isolated montane forest habitats separated by desert lowlands.

Euphilotes pallescens
Pallid Blue, Pale Blue, Pallid Dotted Blue
Euphilotes pallescens is a small lycaenid butterfly endemic to the Great Basin region of western North America. Populations exhibit significant genetic and morphological differentiation among isolated mountain ranges, reflecting long-term isolation in sky-island habitats. The species has a complex evolutionary history involving periods of divergence and potential reticulation. Its restricted distribution and habitat specificity make it a valuable model for studying phylogeography in arid mountain systems.

Hexurellidae
Micro Dwarf Tarantulas
Hexurellidae is a monogeneric family of mygalomorph spiders containing only the genus Hexurella, established in 2019 based on phylogenomic evidence showing it as sister to all remaining atypoids. This relictual lineage diverged from other atypoids approximately 300 million years ago. Members are among the smallest mygalomorph spiders worldwide (2.5–5 mm as adults), with seven recognized species distributed in the US-Mexico borderlands. The family exhibits strict microhabitat preferences and micro-endemism, making it significant for sky island biogeography research.

Mannophorus forreri
Mannophorus forreri is a longhorn beetle in the family Cerambycidae, described by Henry Walter Bates in 1885. It belongs to the tribe Trachyderini, a group known for often brightly colored and patterned species. The species is rarely encountered in collections and appears to have a restricted distribution in the southwestern United States and Mexico. Field observations indicate adults are active in early autumn and visit flowers of yellow composites in mountainous areas of Arizona.

Microhexura
Pygmy Funnel-web Spiders, spruce-fir moss spider (M. montivaga)
Microhexura is a genus of minute mygalomorph spiders endemic to North America, containing two described species: M. montivaga and M. idahoana. The genus represents the sole member of family Microhexuridae. M. montivaga, the spruce-fir moss spider, is restricted to high-elevation spruce-fir forests on isolated peaks in the southern Appalachians and is federally endangered. M. idahoana occurs in old-growth coniferous forests of the Pacific Northwest and northern Rocky Mountains. Both species inhabit moss mats and are among the smallest mygalomorph spiders.

Microhexura montivaga
Spruce-fir moss spider
A miniature mygalomorph spider endemic to the highest peaks of the southern Appalachian Mountains. First described in 1925, this species inhabits moss growing on rocks beneath spruce-fir forest canopy. Listed as federally endangered in 1995 due to severe declines in its montane forest habitat. Genetic studies reveal significant population fragmentation across six allopatric populations, though morphological differences remain minimal.

Milgithea alboplagialis
Milgithea alboplagialis is a small snout moth in the family Pyralidae, first described by Harrison G. Dyar in 1905. It is known only from the Huachuca Mountains in southeastern Arizona, where it inhabits montane environments. The species is characterized by a relatively modest wingspan of 23–27 mm. Like other members of its genus, it belongs to the subfamily Epipaschiinae, a group of pyralid moths whose larvae are generally associated with dead or decaying plant material.

Schizogenius chiricahuanus
Schizogenius chiricahuanus is a ground beetle species in the family Carabidae, described by Whitehead in 1972. It belongs to the tribe Clivinini, a group of small to medium-sized carabids often associated with sandy or loose soil habitats. The species epithet references the Chiricahua Mountains of southeastern Arizona, suggesting a geographic association with this sky island range. Like other members of Schizogenius, it likely exhibits fossorial (burrowing) adaptations.

Timema ritense
Santa Rita timema, Santa Rita Mountains Timema
Timema ritense is a species of walkingstick insect in the family Timematidae, endemic to the Santa Rita Mountains of southern Arizona. The species was originally described as 'Timema ritensis' but underwent a mandatory spelling correction to 'ritense' to match the neuter gender of the genus Timema, following ICZN Article 31.2. Like other members of the genus Timema, it is a small, wingless phasmid with reduced morphology compared to other stick insects. The species is among the few Timema species with documented distribution records, though detailed ecological studies remain limited.

Tricholita ferrisi
Tricholita ferrisi is a small noctuid moth described in 2009, known exclusively from two sky island localities in southeastern Arizona. The species occupies high-elevation coniferous forest habitats in the Madrean Sky Islands region. All known specimens were collected by light trap in late July, suggesting a narrow seasonal activity window.
