Stenochiinae

Guides

• Cibdelis

  Cibdelis is a genus of darkling beetles in the subfamily Stenochiinae, distributed in the Nearctic region. The genus includes at least one well-documented species, Cibdelis blaschkei, which inhabits forested regions of California. Larvae and pupae develop in soft, rotten, dry wood of dead branches on living trees or recently fallen sections. Both life stages possess antipredator defense structures, including urogomphi (pinching organs) on the terminal abdominal segments.

• Polypleurus

  Polypleurus is a genus of darkling beetles in the family Tenebrionidae, subfamily Stenochiinae, tribe Cnodalonini. It was established by Eschscholtz in 1831. The genus is part of the diverse Tenebrionoidea superfamily, which includes numerous species adapted to arid and semi-arid environments. Records indicate approximately 403 observations, suggesting moderate documentation of its species.

• Strongylium

  darkling beetles

  Strongylium is a large genus of darkling beetles (Tenebrionidae: Stenochiinae) containing more than 1,400 described species, making it one of the most species-rich genera in both the family and subfamily. The genus exhibits a broad tropical and subtropical distribution across the Old and New Worlds, with particularly high diversity in the Neotropics (over 300 species). Species-level identification is challenging due to the genus's size and morphological diversity, often requiring specialist knowledge or detailed examination.

• Strongylium crenatum

  Strongylium crenatum is a darkling beetle (Tenebrionidae: Stenochiinae) first described by Mäklin. The species has been documented across much of the eastern and central United States, with 17 states represented in collection records and a first record from Iowa reported as a notable range extension. The genus Strongylium is currently undergoing taxonomic revision, with some species exhibiting distinctive coloration patterns including bright green or metallic markings on the head and pronotum.

• Strongylium cultellatum

  Strongylium cultellatum is a species of darkling beetle in the family Tenebrionidae, subfamily Stenochiinae. Originally described from South America, the species has been documented in India, representing a significant range extension. It belongs to a large genus of long-jointed beetles characterized by elongated bodies and relatively long legs. The species is part of a taxonomically challenging group with ongoing revisionary work.
