Tetracis montanaria
Tetracis montanaria is a recently described geometrid moth species known only from a restricted high-elevation range in southeastern Arizona. Described by Ferris in 2010, it represents one of three new species added to the genus during a major taxonomic revision that synonymized Synaxis with Tetracis. The species inhabits montane aspen-coniferous forests at elevations between 2,440 and 2,715 meters. Adults are active in early autumn, with flight records from early October and possibly late September.
Toxonprucha killamae
Toxonprucha killamae is a moth species described by James T. Troubridge in 2020. It belongs to the genus Toxonprucha within the subfamily Erebinae of the family Erebidae. The species was recently described, and published information remains limited. It is part of the diverse assemblage of underwing and related moths in the Noctuoidea superfamily.
Trichocerapoda harbisoni
Trichocerapoda harbisoni is a species of moth in the family Noctuidae, described by Mustelin in 2006. It belongs to the tribe Eriopygini within the subfamily Noctuinae. The species is known from North America. Very little published information exists regarding its biology or ecology.
Trogloderus warneri
Trogloderus warneri is a species of darkling beetle in the family Tenebrionidae, described by Johnston in 2019. It belongs to a genus of psammophilic beetles restricted to dunes and sandy habitats in the western United States. The species is endemic to the western Colorado Plateau region. As a member of a genus whose most recent common ancestor dates to approximately 5.2 million years ago, T. warneri likely arose during the mid-Pleistocene. The genus Trogloderus comprises six species, all adapted to sandy environments.
Troyus fabulosus
Fabulous Skipper
Troyus fabulosus is a skipper butterfly described by Grishin in 2023. The species is placed in the genus Troyus within the family Hesperiidae. It is known from 379 iNaturalist observations. As a recently described species, detailed biological information remains limited.
Ufeus felsensteini
Ufeus felsensteini is a small noctuid moth described in 2013, known exclusively from the Santa Catalina Mountains in southeastern Arizona. The species exhibits unusual seasonality among temperate moths: adults emerge in spring and enter an overwintering state, with most flight activity occurring during winter months. It is one of the few species in the genus Ufeus, a small noctuid lineage.
Urbanus oplerorum
Urbanus oplerorum is a species of skipper butterfly in the family Hesperiidae, described by Grishin in 2023. It belongs to the genus Urbanus, a group of Neotropical long-tailed skippers. The species was recently described, indicating it was distinguished from congeners through modern taxonomic methods.
Urbanus rickardi
Urbanus rickardi is a species of skipper butterfly in the family Hesperiidae, described by Grishin in 2023. As a recently described species, detailed biological information remains limited. The genus Urbanus comprises long-tailed skippers found primarily in the Americas, though specific traits for U. rickardi have not been independently documented.
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.
Wheelerodemus
Wheelerodemus is a genus of true bugs in the family Blissidae, described by Henry and Sweet in 2015. The genus contains at least one described species, Wheelerodemus muhlenbergiae. Members of this genus are associated with grasses in the genus Muhlenbergia.
Xanthonia hirsuta
Small Juniper Xanthonian
Xanthonia hirsuta is a species of leaf beetle in the family Chrysomelidae, described in 2019. It belongs to the genus Xanthonia, which comprises small, often cryptically colored beetles associated with coniferous vegetation. The species epithet 'hirsuta' refers to the hairy or setose body surface. As a member of the Eumolpinae subfamily, it is likely associated with feeding on gymnosperm foliage, though specific host records remain limited.
Xanthonia nitida
Black Texas Xanthonian
Xanthonia nitida is a species of leaf beetle in the family Chrysomelidae, described in 2019. It is known from Texas and is recognized by its dark coloration. As a member of the genus Xanthonia, it belongs to a group of small leaf beetles that are often associated with vegetation in various habitats. The species is relatively recently described and appears to be uncommon, with limited observation records.
Xanthonia picturata
Common Texas Oak Xanthonia
Xanthonia picturata is a leaf beetle in the family Chrysomelidae, described in 2019 from Texas. It is one of several recently described species in the genus Xanthonia, a group of small leaf beetles associated with oak trees. The species is relatively well-documented through citizen science observations, with over 100 records on iNaturalist. Its common name reflects its apparent association with oak habitats in Texas.
Xanthonia querci
Xanthonia querci is a species of flea beetle in the family Chrysomelidae, described in 2019. The species epithet "querci" indicates an association with oaks (Quercus). As a member of the tribe Alticini, it possesses the enlarged hind femora characteristic of flea beetles, enabling jumping locomotion. The genus Xanthonia contains multiple North American species, many of which are associated with woody host plants.
Xanthonia texana
Xanthonia texana is a species of leaf beetle in the family Chrysomelidae, subfamily Eumolpinae. It was described in 2019 from Texas, representing a relatively recent addition to the genus Xanthonia. The genus comprises small leaf beetles, many of which are associated with specific host plants. As a recently described species, detailed natural history information remains limited.
