Araeoschizus
Araeoschizus is a genus of darkling beetles (family Tenebrionidae) in the tribe Stenosini. The genus was established by John Lawrence LeConte in 1851. Members of this genus are part of the subfamily Pimeliinae, a diverse group of tenebrionids often associated with arid and semi-arid environments. The genus is native to western North America.
Barilepton
flower weevils
Barilepton is a genus of weevils in the family Curculionidae, established by John Lawrence LeConte in 1876. The genus contains approximately 13 described species, commonly referred to as flower weevils. Members of this genus are part of the diverse and economically significant weevil family, though specific biological details for the genus remain poorly documented. The genus is represented by very few observation records, suggesting it may be rarely encountered, understudied, or restricted to specific habitats.
Dryotribus
Dryotribus is a genus of weevils in the family Curculionidae, established by George Henry Horn in 1873. The genus contains four described species: D. amplioculus, D. mimeticus, D. solitarius, and D. wilderi. These beetles belong to the diverse beetle superfamily Curculionoidea, which is characterized by the distinctive elongated snout or rostrum typical of weevils. The genus is relatively poorly documented in scientific literature, with limited published information on its biology and ecology.
Kalissus
Kalissus is a genus of rove beetles (Staphylinidae) in the subfamily Micropeplinae, established by John Lawrence LeConte in 1874. Members of this genus are small beetles characterized by their reduced elytra that leave much of the abdomen exposed, a defining feature of the family. The genus is part of the diverse Staphylinoidea superfamily, which contains thousands of species worldwide. Specific ecological and behavioral details for Kalissus remain poorly documented in available literature.
Lissagria
Lissagria is a genus of rove beetles in the family Staphylinidae, established by Casey in 1906. It belongs to the tribe Falagriini within the subfamily Aleocharinae. The genus contains approximately eight described species, primarily named by Casey and other early 20th-century coleopterists.
Loberus
pleasing fungus beetles
Loberus is a genus of pleasing fungus beetles in the family Erotylidae, first described by John Lawrence LeConte in 1861. The genus comprises approximately 13-16 described species and is classified within the subfamily Loberinae. These beetles are part of the diverse Erotylidae family, which is characterized by association with fungal substrates. The genus is recognized in major taxonomic databases including Catalogue of Life and GBIF.
Pergetus
Pergetus is a genus of antlike flower beetles in the family Anthicidae, established by Casey in 1895 based on Eurygenius campanulatus LeConte, 1874. The genus currently contains at least two described species: Pergetus campanulatus and Pergetus wilati. A 1960 taxonomic revision redefined the genotype using both male and female characters and established the genus limits. Members of this genus are small beetles that superficially resemble ants in their morphology and movement.
Thrimolus
hairy fungus beetles
Thrimolus is a genus of hairy fungus beetles in the family Mycetophagidae, established by Thomas L. Casey in 1900. The genus contains at least two described species: Thrimolus duryi and Thrimolus minutus. As members of Mycetophagidae, these beetles are associated with fungal habitats. The genus is placed in the tribe Typhaeini within the subfamily Mycetophaginae.
Toramus
pleasing fungus beetles
Toramus is a genus of pleasing fungus beetles in the family Erotylidae, containing nine described species. These small beetles are associated with fungal habitats and are found primarily in North America. The genus was established by Grouvelle in 1916 and is classified within the tribe Toramini.
Triachus
case-bearing leaf beetles
Triachus is a small genus of case-bearing leaf beetles in the family Chrysomelidae, established by J.L. LeConte in 1880. The genus contains five described species distributed in North America. Members of this genus are classified within the tribe Clytrini, which is characterized by larvae that construct portable cases from their own fecal material mixed with plant debris. Adults are leaf-feeding beetles.
Xeranobium
death-watch beetles
Xeranobium is a genus of death-watch beetles in the family Ptinidae, established by Fall in 1905. The genus contains approximately 13 described species. Death-watch beetles (family Ptinidae) are wood-boring beetles known for the distinctive tapping sounds produced by males to attract mates. Members of Xeranobium share the general characteristics of this group, though species-level details remain limited in available literature.
