Alaephus
Alaephus is a genus of darkling beetles in the family Tenebrionidae, established by G.H. Horn in 1870. It belongs to the subfamily Pimeliinae and tribe Vacronini. The genus is poorly documented in the literature, with limited information available on its species diversity, biology, and ecology.
Alaudes
Alaudes is a genus of darkling beetles in the family Tenebrionidae, subfamily Pimeliinae, tribe Cnemeplatiini. The genus was revised in 2018, resulting in the description of new species from the southwestern United States and Mexico. It belongs to the subtribe Alaudina, which was established as part of that revisionary work. Members of this genus are part of a diverse radiation of tenebrionid beetles adapted to arid and semi-arid environments.
Anchomma
Anchomma is a genus of darkling beetles (family Tenebrionidae) established by John Lawrence LeConte in 1858. It belongs to the subfamily Pimeliinae, tribe Stenosini, and subtribe Dichillina. The genus is characterized by morphological features typical of the subtribe Dichillina, including adaptations associated with arid environments. Knowledge of this genus is limited due to its rarity in collections and few documented observations.
Anepsiini
Anepsiini is a tribe of darkling beetles within the subfamily Pimeliinae of the family Tenebrionidae. It was established by J.L. LeConte in 1862. The tribe contains at least four genera distributed in North America. Members of this tribe are part of a diverse group of beetles commonly known as darkling beetles, which are primarily associated with arid and semi-arid environments.
Auchmobius
Auchmobius is a genus of darkling beetles in the family Tenebrionidae, subfamily Pimeliinae, and tribe Edrotini. It was established by John Lawrence LeConte in 1851. The genus belongs to a group of beetles commonly associated with arid and semi-arid environments. Species within Auchmobius are poorly documented in scientific literature, with limited published information on their biology and ecology.
Batulius
Batulius is a genus of darkling beetles in the family Tenebrionidae, subfamily Pimeliinae, and tribe Anepsiini. Established by J.L. LeConte in 1851, this genus belongs to the diverse group of tenebrionid beetles commonly associated with arid and semi-arid environments. The genus is part of the Anepsiini tribe, which contains species adapted to dry habitats. Information on species diversity and biology within Batulius remains limited in available literature.
Branchus
Branchus is a genus of darkling beetles in the family Tenebrionidae, subfamily Pimeliinae, and tribe Branchini. The genus was established by John Lawrence LeConte in 1862. It is placed within the speciose superfamily Tenebrionoidea, which includes many arid-adapted beetle lineages. The genus name derives from Greek mythology, though this etymological connection has no biological significance.
Cnemeplatiini
Cnemeplatiini is a tribe of darkling beetles within the subfamily Pimeliinae. The tribe comprises approximately nine genera distributed across multiple biogeographic regions including the Palearctic, Indomalaya, tropical Africa, Australasia, and the Americas. Members are classified in the family Tenebrionidae, a large and diverse group of beetles commonly known as darkling beetles.
Cnemodinini
Cnemodinini is a tribe of darkling beetles (Tenebrionidae) established by Gebien in 1910. It belongs to the subfamily Pimeliinae, a diverse group of predominantly xerophilic beetles adapted to arid and semi-arid environments. The tribe contains multiple genera distributed across arid regions, though specific taxonomic boundaries and included genera have been subject to revision. Members share characteristics typical of Pimeliinae, including adaptations to dry habitats.
Coniontini
Coniontini is a tribe of darkling beetles within the subfamily Pimeliinae of the family Tenebrionidae. The tribe contains at least four genera distributed in North America. Notable included genera are Coelus (dune beetles), Coniontis, Conisattus, and Eusattus. Members are ground-dwelling beetles associated with arid and sandy environments.
Coniontis
Coniontis is a genus of darkling beetles (family Tenebrionidae) in the tribe Coniontini. The genus was established by Eschscholtz in 1829 and contains multiple species distributed primarily in western North America. These beetles are generally associated with arid and semi-arid habitats. The genus is well-represented in entomological collections and citizen science observations.
Eschatomoxys
Eschatomoxys is a genus of darkling beetles in the family Tenebrionidae, subfamily Pimeliinae, tribe Edrotini. The genus was established by Blaisdell in 1935 and is distributed in the Nearctic region. As a member of the Edrotini, it belongs to a tribe of arid-adapted tenebrionids often associated with desert and semi-desert environments. The genus has received taxonomic revision but published biological details remain limited.
Nyctoporis
Nyctoporis is a genus of darkling beetles in the family Tenebrionidae, established by Eschscholtz in 1831. The genus comprises five described species distributed in North America. These beetles belong to the subfamily Pimeliinae and tribe Nyctoporini. Members of this genus are part of the diverse tenebrionid fauna characteristic of arid and semi-arid regions of western North America.
Stenomorpha
Stenomorpha is a large genus of darkling beetles (family Tenebrionidae) comprising more than 160 described species and subspecies. The genus was established by Solier in 1836 and belongs to the tribe Asidini within subfamily Pimeliinae. Species-level taxonomy has been historically neglected, with no modern revision for nearly 175 years until recent work by Keller (2008) and others. The genus exhibits notable diversity in the southwestern United States and Mexico, with some species occurring in specialized habitats including California vernal pools and the Cuatrociénegas Protected Area in Coahuila, Mexico.
Stenomorpha furcata
Stenomorpha furcata is a darkling beetle in the family Tenebrionidae, subfamily Pimeliinae, tribe Asidini. Originally described by Champion in 1892, it was transferred to the genus Stenomorpha by Smith, Miller, and Wheeler in 2011 as part of a taxonomic revision that established the informal 'furcata species group' within Stenomorpha. This group comprises four species: S. furcata, S. roosevelti, S. wickhami, and S. granicollis. The species has been documented in Texas, USA, where it has been observed at night near blacklight setups in juniper chaparral habitat.
Stenomorpha horrida
Stenomorpha horrida is a species of darkling beetle in the family Tenebrionidae, tribe Asidini. First described by Champion in 1892, this flightless beetle belongs to a large genus historically comprising 88 species with limited modern taxonomic revision until recent work by Fran Keller and colleagues. The species is known from Mexico, though specific habitat and ecological details remain poorly documented in published literature. Like other Stenomorpha species, it likely inhabits arid or semi-arid environments given the genus's association with such habitats.
Stenosini
darkling beetles
Stenosini is a tribe of darkling beetles (family Tenebrionidae, subfamily Pimeliinae) containing over 40 genera. Members are generally small-bodied and have a pantropical distribution. The tribe is characterized by specific morphological features including non-divided eyes and distinctive antennal proportions. Some species are associated with ants, rodent nests, and soil.
Triorophus
Triorophus is a genus of darkling beetles (family Tenebrionidae) within the tribe Edrotini. The genus was established by J.L. LeConte in 1851. Members of this genus are part of the subfamily Pimeliinae, a group often associated with arid and semi-arid environments. The genus contains multiple species distributed in North America, particularly in western regions.
Typhlusechus
Typhlusechus is a genus of darkling beetles in the family Tenebrionidae, described by Linell in 1897. It belongs to the tribe Stenosini within the subfamily Pimeliinae. The genus is rarely encountered in collections and field observations, with minimal published biological information available.
Vacronini
Vacronini is a tribe of darkling beetles within the subfamily Pimeliinae, family Tenebrionidae. The tribe was established by Gebien in 1910 and comprises at least four genera with a disjunct distribution across North America and Australasia. Members are classified within the superfamily Tenebrionoidea, a diverse group of beetles commonly associated with arid and semi-arid environments.
