Anaplectoides brunneomedia
Brown-lined Dart
Anaplectoides brunneomedia, commonly known as the brown-lined dart, is a noctuid moth restricted to a few localities in the Appalachian Mountains. The species was described by McDunnough in 1946 and remains poorly known due to its limited distribution and rarity. Adults are active during summer months. The specific epithet 'brunneomedia' refers to the brown median line on the forewing.
Anillinus choestoea
Anillinus choestoea is a small, eyeless ground beetle in the family Carabidae, described by Thomas C. Barr in 1962. It belongs to a genus of anilline beetles characterized by reduced eyes or complete anophthalmia, elongated bodies, and subterranean habits. The species is known from cave and deep soil habitats in the Appalachian region of the eastern United States. Like other members of Anillinus, it exhibits morphological adaptations for life in darkness, including depigmentation and elongated appendages.
Apheloria montana
mountain cherry millipede
Apheloria montana is a large flat-backed millipede in the family Xystodesmidae, native to the southern Appalachian Mountains of eastern Tennessee and western North Carolina. It serves as the type species for the genus Apheloria. The species produces hydrogen cyanide and benzaldehyde as chemical defenses, which emit a characteristic cherry or almond odor. Its bright yellow or orange spots function as aposematic coloration warning predators of its toxicity.
Arianops unicoi
Arianops unicoi is a species of ant-loving beetle in the family Staphylinidae, described by Barr in 1974. The specific epithet 'unicoi' references the Unicoi Mountains, part of the southern Appalachian range in eastern Tennessee and western North Carolina. As a member of the subfamily Pselaphinae, it belongs to a diverse group of small rove beetles typically associated with forest floor habitats. The species is known from a restricted geographic range in the southeastern United States.
Bombus flavidus appalachiensis
A subspecies of the cuckoo bumble bee Bombus flavidus endemic to eastern North America, ranging from the Appalachian Mountains to the eastern boreal regions of the United States and far southeastern Canada. Described in 2021 following integrative taxonomic analysis that revealed this population as genetically and morphologically distinct from western North American and Palearctic populations. As a social parasite, this subspecies does not construct colonies or collect pollen but invades nests of other bumble bee species.
Brachycybe petasata
Brachycybe petasata is a small millipede in the order Platydesmida, endemic to the southern Appalachian Mountains of the southeastern United States. It inhabits moist forest floor habitats, particularly leaf litter and decaying wood in beech, birch, maple, and hemlock forests. The species is distinguished by its production of four unique monoterpene alkaloids as chemical defenses: gosodesmine, hydrogosodesmine, homogosodesmine, and hydrohomogosodesmine. As a member of the subterclass Colobognatha, it represents one of the few millipede lineages known to synthesize terpenoid alkaloids.
Cherokeea attakullakulla
Cherokee Moth
Cherokeea attakullakulla is a small, inconspicuous moth in the family Noctuidae and the sole member of its genus. The species was described in 2014 from specimens collected in the southern Appalachian Mountains of North Carolina and Georgia. It is associated with canebrake habitats dominated by native bamboo species. The specific epithet honors Chief Attakullakulla of the Cherokee Nation, who represented his people in treaty negotiations in 1730, and recognizes the Cherokee as stewards of the region's habitats.
Cryptocercus punctulatus
brown-hooded cockroach, woodroach, wingless wood roach, eastern wood-eating cockroach
Cryptocercus punctulatus is a wingless, wood-feeding cockroach endemic to montane forests of the eastern United States. It is one of the few subsocial cockroach species, exhibiting extended biparental care of offspring over multiple years. The species harbors obligate cellulolytic flagellate symbionts in its hindgut, transferred to neonates through proctodeal trophallaxis by parents. Its life history—xylophagy, social behavior, and gut symbiosis—makes it a key model for understanding the evolutionary origins of termite eusociality.
Dineutus serrulatus
whirligig beetle
Dineutus serrulatus is a species of whirligig beetle in the family Gyrinidae, first described by LeConte in 1868. The species occurs in the Appalachian Mountains of the southeastern United States, with records from northeastern Georgia and the southwestern Carolinas. A subspecies, D. s. analis, has been recorded from Kansas and the southeastern United States.
Dioryctria yatesi
Mountain Pine Coneworm, Mountain Pine Coneworm Moth
Dioryctria yatesi, commonly known as the mountain pine coneworm, is a species of snout moth in the family Pyralidae. It was described by Mutuura and Munroe in 1979 and is restricted to the mountains of the coastal southeastern United States and Tennessee. The larvae are specialized cone borers that feed on Pinus pungens (Table Mountain pine).
Eucopina tocullionana
white pine cone borer, White Pine Coneborer Moth
A small tortricid moth specialized on pine cones. Adults are active in spring and summer, with larvae developing within cones of white pine and Virginia pine. The species is restricted to eastern North America, primarily in Appalachian and Great Lakes regions.
Fumontana
Fumontana is a monotypic genus of harvestman (Opiliones: Laniatores) containing the single species F. deprehendor. It is considered an ancient relict lineage with Gondwanan affinities, currently restricted to the southern Appalachian Mountains of the eastern United States. The genus name derives from Latin words for 'smoke' and 'mountain', referencing its discovery in the Great Smoky Mountains.
Horologion hubbardi
Horologion hubbardi is a newly described species of carabid beetle from Bath County, Virginia. It represents only the second known species in the genus Horologion, which was previously known solely from a single holotype collected in West Virginia in 1931. DNA sequence data and morphological analysis place the genus in the supertribe Trechitae, as sister to the Gondwanan tribe Bembidarenini. The species is considered a relict lineage with no close relatives known in the Northern Hemisphere.
Hypochilus thorelli
Thorell's Lampshade-web Spider, lampshade spider
Hypochilus thorelli is a relictual spider species notable for possessing four book lungs—a trait shared with mesothele and mygalomorph spiders but unique among araneomorphs. The species constructs distinctive lampshade-shaped webs on the undersides of overhangs in humid Appalachian forests. First described by George Marx in 1888, it serves as the type species for both its genus and family. Its combination of primitive respiratory anatomy with derived silk-producing structures makes it significant for spider phylogenetics.
Idia laurentii
Laurentine Idia, Appalachian Idia
Idia laurentii is a litter moth in the family Erebidae, first described by J. B. Smith in 1893. It is endemic to the Appalachian region of the eastern United States, ranging from central New York south to the mountains of North Carolina. The species has a univoltine life cycle with one generation per year. Larvae have been documented feeding on dead cherry leaves.
Leucorrhinia hudsonica
Hudsonian Whiteface
Leucorrhinia hudsonica, the Hudsonian Whiteface, is a dragonfly species in the family Libellulidae. Its common name derives from its association with the Hudson Bay region. The species has disjunct, regionally rare populations in the Appalachian Mountains. As a member of the genus Leucorrhinia, it shares characteristics with other whiteface dragonflies, including the distinctive pale facial coloration that gives the group its common name.
Orfelia fultoni
Foxfire Fly, dismalites
Orfelia fultoni is the only bioluminescent fly species known from North America. The larvae, commonly called 'dismalites' or 'glowworms,' produce the bluest light (~460 nm) of any studied bioluminescent insect. Larvae are carnivorous predators that construct sticky webs along stream banks and in caves, using paired bioluminescent lanterns to lure flying prey. Adults are non-feeding and short-lived. The species was discovered in 1940 near Glenville, North Carolina by B.B. Fulton and described by Elizabeth Gault Fisher.
Papilio appalachiensis
Appalachian Tiger Swallowtail
Papilio appalachiensis is a swallowtail butterfly endemic to the Appalachian Mountains of eastern North America. It originated through hybrid speciation between Papilio canadensis and Papilio glaucus, and is now recognized as a distinct species with stable populations at higher elevations. Adults are notably larger than both parental species, with wingspans of 86–115 mm. The species is univoltine, with adults emerging in May and females ovipositing during a brief spring flight period.
Protoplasa fitchii
Protoplasa fitchii is a species of primitive crane fly in the family Tanyderidae. It is one of the few North American representatives of this relict family, which retains many ancestral dipteran characteristics. The species is primarily known from eastern North America, where larvae develop in aquatic or semi-aquatic habitats. Adults are rarely encountered and poorly studied.
Pyrgus centaureae wyandot
Appalachian Grizzled Skipper
Pyrgus centaureae wyandot is a subspecies of northern grizzled skipper endemic to the Appalachian Highlands and Northern Michigan. It is a small butterfly with distinctive checkered wing patterns and low, erratic flight. The subspecies is listed as federally threatened and state endangered in Ohio and New Jersey due to habitat loss and pesticide exposure. Populations have declined significantly from insecticide spraying targeting spongy moth outbreaks.
