Guides
Argoporis alutacea
Argoporis alutacea is a species of darkling beetle in the family Tenebrionidae, described by Casey in 1890. The genus Argoporis is part of a diverse group of beetles commonly found in arid and semi-arid environments. Very little specific biological information has been published for this species. Records indicate a distribution in Mexico.
Blapstinus castaneus
Blapstinus castaneus is a species of darkling beetle in the family Tenebrionidae, described by Thomas Lincoln Casey Jr. in 1890. The genus Blapstinus comprises small to medium-sized tenebrionid beetles found primarily in arid and semi-arid regions of North America. As a member of this genus, B. castaneus is likely adapted to dry environments. The species is represented by limited specimen records in museum collections and few observations in citizen science databases.
Blapstinus fuscus
Blapstinus fuscus is a species of darkling beetle in the family Tenebrionidae. It belongs to the tribe Blapstinini, a group of small to medium-sized tenebrionids primarily distributed in the Americas. The species was described by Thomas L. Casey in 1890. Available records indicate a distribution in Mexico, though specific ecological details remain poorly documented in published literature.
Conibius uniformis
A darkling beetle species described by Casey in 1890. The specific epithet 'uniformis' refers to the species' uniform coloration. It is one of several species in the genus Conibius, a group of small to medium-sized tenebrionid beetles found in arid and semi-arid regions of North America. The species is documented from Mexico based on collection records.
Cybotus
Cybotus is a genus of darkling beetles in the family Tenebrionidae, established by Casey in 1890. It is a small genus with limited documented species, occurring in the Neotropical region. The genus belongs to the speciose family Tenebrionidae, which contains over 20,000 species of primarily detritivorous beetles. Information on Cybotus remains sparse in published literature.
Helops callosus
Helops callosus is a darkling beetle in the family Tenebrionidae, described by Casey in 1890. The genus Helops belongs to a group of darkling beetles that can be challenging to distinguish from ground beetles (Carabidae) without close examination. Members of this genus exhibit some characteristics that blur typical distinctions between carabids and tenebrionids, such as antennae structure that resembles ground beetles while retaining concealed mandibles typical of darkling beetles.
Trichocnemis spiculatus neomexicanus
New Mexican ponderous borer
Trichocnemis spiculatus neomexicanus is a subspecies of the ponderous borer, a large prionine longhorn beetle native to western North America. The larvae are among the largest of any North American cerambycid, developing in dead or dying coniferous wood—particularly ponderosa pine. Adults are nocturnal and attracted to lights. This subspecies was described by Casey in 1890 and occurs in the southwestern United States and Mexico. The species has gained notoriety as the inspiration for modern chainsaw design, after Joe Cox observed the larva's opposable mandibles in action.
Ulus fimbriatus
Ulus fimbriatus is a species of darkling beetle in the family Tenebrionidae, described by Thomas L. Casey in 1890. The genus Ulus is a small group within this diverse beetle family. Published records indicate this species occurs in Mexico. Information on its biology and ecology remains limited in accessible literature.
Xerolinus dispar
Xerolinus dispar is a species of darkling beetle in the family Tenebrionidae. The genus Xerolinus is associated with arid and semi-arid habitats. No specific biological information has been documented for this particular species beyond its taxonomic description.
