Tarache
Tarache is a genus of moths in the family Noctuidae, subfamily Acontiinae, erected by Jacob Hübner in 1823. The genus comprises primarily New World species, most of which were formerly classified under the genus Acontia. Taxonomic authorities differ on its status: Catalogue of Life treats Tarache as accepted, while GBIF and some lepidopteran resources list it as a synonym of Acontia. The genus includes approximately 50 described species arranged in three main species groups (aprica, bilimeki, and lucasi groups).
Telebasis salva
Desert Firetail
Telebasis salva, commonly known as the desert firetail, is a species of narrow-winged damselfly in the family Coenagrionidae. It was first described by Hagen in 1861 under the basionym Agrion salva. The species has a broad distribution across the Americas, ranging from North America through Central America to South America. The IUCN lists it as Least Concern (LC) with a stable population, last reviewed in 2018.
Tetracha
Metallic Tiger Beetles
Tetracha is a genus of metallic tiger beetles in the family Cicindelidae, containing approximately 100 described species. The genus was formerly treated as a subgenus of Megacephala but was elevated to full generic status based on morphological and molecular evidence. Tetracha species are exclusively New World in distribution, contrasting with the Old World distribution of Megacephala. Four species occur in the United States: T. carolina, T. floridana, T. virginica, and T. impressa.
Thopeutis
grass moth
Thopeutis is a genus of grass moths in the family Crambidae, subfamily Crambinae, and tribe Haimbachiini. It was established by Hübner in 1818. The genus contains six described species distributed primarily in the Americas. Some historical classifications incorrectly placed it in Pyralidae.
Tillinae
checkered beetles (subfamily)
Tillinae is a subfamily of checkered beetles (family Cleridae) comprising approximately 164 described species across 11 genera in the New World. The subfamily is characterized by diagnostic morphological features including procryptosternum fused to pronotal extension, closed procoxal cavities, and 5-5-5 tarsal formula. Body size ranges from 3 to 40 mm. The genus Cymatodera dominates the subfamily with approximately 134 species, exhibiting its greatest diversity in Mexico.
Titanoecidae
Rock Weavers
Titanoecidae is a family of cribellate spiders comprising five genera and approximately 67 species. Members are primarily dark-colored web-builders that construct woolly, cribellate silk webs. The family occurs across the New World and Eurasia, with several species inhabiting high-altitude mountain environments where they can achieve high local abundance. The family was elevated from Amaurobiidae by Lehtinen in 1967.
Toxomerus politus
maize calligrapher
Toxomerus politus, commonly known as the maize calligrapher, is a small hoverfly (Diptera: Syrphidae) measuring 8–9 mm. The species is native to North America but has been introduced and is expanding its distribution across Central and South America, with recent records from Chile. Adults and larvae are associated with corn (Zea mays), feeding on pollen. The species has been studied for its male genitalia morphology and sperm ultrastructure using advanced microscopy techniques.
Trachelas
Trachelas is a genus of hunting spiders in the family Trachelidae, established by Ludwig Carl Christian Koch in 1872. The genus contains approximately 99 species with worldwide distribution across tropical, subtropical, and temperate regions. Trachelas sensu stricto is restricted to the Old World, while New World species represent a distinct lineage only distantly related to the core group. The genus has undergone significant taxonomic revision, with species previously assigned to Corinnidae now placed in Trachelidae.
Trachyderini
Trachyderini is a tribe of long-horned beetles (Cerambycidae: Cerambycinae) comprising at least 140 genera and 650 described species. Members are predominantly diurnal, medium to large-sized, and frequently exhibit bright coloration. The tribe has a primarily New World distribution, with notable diversity in southwestern North America, Mexico, Central America, and South America, though some genera extend into the Palearctic region including Mongolia. Several genera display striking mimicry of wasps or other beetles.
Triepeolus simplex
cuckoo bee
Triepeolus simplex is a cleptoparasitic bee species in the family Apidae, described by Robertson in 1903. It belongs to the simplex species group, characterized by females possessing a trapezoidal or triangular pseudopygidial area with bright, reflective setae and a concave apical margin. As a cuckoo bee, it does not construct nests or collect pollen but instead parasitizes the nests of other bee species. The species occurs in North America and is part of an entirely New World group of Triepeolus species.
Uramyini
Uramyini is a tribe of tachinid flies (Diptera: Tachinidae) within the subfamily Dexiinae, distributed in the New World. Members are characterized by a distinctive combination of morphological traits including bare prosternum, bare arista, haired eyes, and a cylindrical body plan. The tribe has been documented to contain parasitoid species that attack caterpillars, particularly those in the family Megalopygidae. Taxonomic placement of Uramyini remains under discussion, with some evidence suggesting it may represent a nested sub-clade within Voriini.
Urosigalphus
A genus of braconid wasps comprising over 100 described species distributed across North, Central, and South America. Species in this genus are parasitoids, with documented associations including beetle hosts in families Bruchidae and Curculionidae. Colombian species have been collected primarily from forest understories using Malaise traps.
Valgus
Valgus is a genus of small scarab beetles in the family Scarabaeidae, subfamily Cetoniinae. Most described species occur in Asia, with some extending into northern Africa and Europe. Three species are native to the New World, and one species is found in South Africa. Adults are characterized by their strongly flattened bodies and distinctive scale-like setae covering both dorsal and ventral surfaces.
Vazquezitocoris
Vazquezitocoris is a genus of leaf-footed bugs in the family Coreidae, established by Brailovsky in 1990. The genus comprises approximately 14 described species distributed across the Americas, from the southwestern United States through Central America to South America. Members of this genus belong to the tribe Hypselonotini within the subfamily Coreinae. As true bugs in the order Hemiptera, species in this genus possess piercing-sucking mouthparts characteristic of the group.
Warwickia
May beetles, junebugs
Warwickia is a genus of scarab beetles in the subfamily Melolonthinae, established in 2005. It contains one described species, Warwickia pilosa. The genus belongs to the tribe Warwickiini, which was erected to accommodate this taxon. Warwickia represents a relatively recent addition to the classification of New World scarab beetles.
Xyonysius basalis
Xyonysius basalis is a seed bug species in the family Lygaeidae, first described by Dallas in 1852. The species has a broad distribution across the Americas, ranging from the Caribbean through Central America to North and South America. It belongs to the subfamily Orsillinae and tribe Metrargini. Available information on its biology and ecology remains limited.
Zanysson
Zanysson is a strictly New World genus of digger wasps in the family Crabronidae, subfamily Bembicinae. The genus was established by Rohwer in 1921 and remained taxonomically stagnant for over 80 years until the description of Z. gemmatus from Colombia in 2007. Members are assumed to be cleptoparasites of other crabronid wasps, though direct biological observations are lacking for most species. The genus includes at least three described species distributed from the southwestern United States through Mexico to northwestern South America.
Zelus nugax
Zelus nugax is a species of assassin bug in the family Reduviidae, first described by Stål in 1862. As a member of the genus Zelus, it possesses the characteristic sticky forelegs used to capture prey, a trait that has earned these insects the common name 'sundew assassin bugs.' The species is distributed across the Americas, with records from the Caribbean, Middle America, North America, and South America. Like other Zelus species, it is a predatory insect that feeds on other small arthropods.
Zopherini
A tribe of beetles within the family Zopheridae, characterized by heavily sclerotized bodies and a primarily New World distribution. The tribe comprises multiple genera including Noserinus, Nosoderma, Phloeodes, Sesaspis, and Verodes. A 2008 phylogenetic analysis revised the generic classification, elevated Sesaspis from synonymy, and described two new Central American species.
