Trechus barberi
Trechus barberi is a species of ground beetle in the family Carabidae, originally described by Jeannel in 1931 as Microtrechus barberi. It belongs to the large genus Trechus, which contains numerous small carabid beetles found primarily in the Northern Hemisphere. The species is recorded from the United States, though specific details about its biology and ecology remain limited in available sources.
Trechus tuckaleechee
Trechus tuckaleechee is a species of ground beetle in the subfamily Trechinae, described by Barr in 1962. It belongs to the genus Trechus, a large and widespread group of small carabid beetles commonly known as blind beetles or trechine ground beetles. The species epithet 'tuckaleechee' likely references Tuckaleechee, a location in Tennessee, USA, suggesting a restricted geographic distribution. Like other Trechus species, it is presumably adapted to subterranean or cryptic habitats.
Trechus vandykei pisgahensis
A subspecies of ground beetle in the family Carabidae, described by Barr in 1979. This taxon belongs to the genus Trechus, a diverse group of small carabid beetles commonly known as ground beetles. The subspecific epithet 'pisgahensis' suggests an association with Pisgah, likely referring to a geographic location in the southeastern United States.
Trichadenotecnum desolatum
Trichadenotecnum desolatum is a species of barklouse in the family Psocidae, originally described by Chapman in 1930 as Psocus desolatus. It belongs to the genus Trichadenotecnum, a group of small, winged psocids commonly found on tree bark and foliage. The species is known from the southern United States and Mexico. Like other members of its family, it likely inhabits woody vegetation and feeds on microflora.
Trochosa abdita
Trochosa abdita is a wolf spider (family Lycosidae) described by Gertsch in 1934. It belongs to the genus Trochosa, a group of ground-dwelling hunting spiders characterized by their distinctive eye arrangement. The species is known only from the United States, though specific details about its ecology and behavior remain poorly documented in the scientific literature.
Trox frontera
Trox frontera is a hide beetle in the family Trogidae, first described by Vaurie in 1955. It is currently treated as a synonym of Glyptotrox frontera. Members of this genus are cryptic beetles that specialize in consuming dried animal remains, including skin, hair, feathers, and connective tissue. They are among the final colonizers of carcasses, arriving after most other insects have departed.
Tytthus wheeleri
Tytthus wheeleri is a species of plant bug in the family Miridae, described by Henry in 2012. The species is distributed across the southeastern and central United States, with records from South Carolina, Arkansas, Florida, Georgia, Kansas, Nebraska, Texas, and Virginia. As a member of the genus Tytthus, it belongs to a group of small predatory mirids.
Valenzuela nadleri
Valenzuela nadleri is a species of lizard barklouse in the family Caeciliusidae, described by Mockford in 1966. It is native to North America, with confirmed records from the United States. Like other members of the genus Valenzuela, it is a small, winged barklouse that inhabits bark and lichen microhabitats. The specific epithet honors nematologist Steve Nadler, professor and chair of the UC Davis Department of Entomology and Nematology.
Wormaldia arizonensis
Wormaldia arizonensis is a species of caddisfly in the family Philopotamidae, originally described by Ling in 1938. It belongs to the second largest genus in its family, with approximately 175 extant species worldwide. The species is known from the southwestern United States and Mexico. As with other philopotamid caddisflies, it is presumed to have aquatic larval stages and terrestrial adult stages, though specific details of its biology remain poorly documented.
Xenotrechus denticollis
Southern Xenotrechus Cave Beetle
Xenotrechus denticollis is a troglobitic ground beetle in the family Carabidae, described by Barr & Krekeler in 1967. It belongs to a genus of cave-dwelling beetles endemic to the southern United States. The species epithet 'denticollis' refers to toothed characteristics of the pronotum or neck region.
Xeropsamobeus desertus
Xeropsamobeus desertus is a species of aphodiine dung beetle in the family Scarabaeidae. It is found in desert regions of southwestern North America and northwestern Mexico. The species was described by Van Dyke in 1918.
Xysticus apachecus
Xysticus apachecus is a species of crab spider in the family Thomisidae, first described by Gertsch in 1933. Like other members of the genus Xysticus, it is a ground-dwelling ambush predator characterized by its crab-like leg posture and sideways movement. The species is known from the United States, though specific details about its ecology and behavior remain limited in the published literature.
Xysticus pellax
Xysticus pellax is a species of crab spider in the family Thomisidae, first described by O. Pickard-Cambridge in 1894. It is native to North America, with records from Canada and the United States. Like other members of its genus, it is a ground-dwelling ambush predator.
Yumachrysa unidentified-sp-texas
Yumachrysa unidentified-sp-texas is an undescribed or poorly documented species of green lacewing in the family Chrysopidae, subfamily Nothochrysinae. It represents a taxon recognized from specimens collected in Texas that has not been formally described in the scientific literature. Members of the genus Yumachrysa are relatively uncommon and understudied compared to other chrysopid genera. This taxon is distinguished from described Yumachrysa species by subtle morphological differences, though formal diagnostic characters remain unpublished.
Zelotes duplex
ground spider
Zelotes duplex is a species of ground spider in the family Gnaphosidae, first described by Chamberlin in 1922. It is found in the United States and Canada. As a member of Zelotes, it belongs to a large genus of active hunting spiders commonly known as ground spiders.
Zygona duplex
Zygona duplex is a species of soil-dwelling centipede in the family Geophilidae, described by Chamberlin in 1960. It belongs to the order Geophilomorpha, which comprises the most diverse group of centipedes characterized by their elongated, worm-like bodies with numerous leg pairs. The species is known from the United States.
