Blaptinae
Guides
Amphidorini
Amphidorini is a tribe of darkling beetles (Tenebrionidae) comprising six genera, all native to North America. The tribe was reclassified in 2021 from Tenebrioninae to the resurrected subfamily Blaptinae based on phylogenetic research. The genus Eleodes (desert stink beetles) is the most diverse and widely distributed member, extending into the Neotropics. In 2022, the South American genus Nycterinus was removed from Amphidorini and placed in incertae sedis within Tenebrioninae.
Lariversius
Lariversius is a monotypic genus of darkling beetles (family Tenebrionidae) described by Blaisdell in 1947. The genus contains a single species, Lariversius tibialis. It belongs to the tribe Amphidorini within the subfamily Blaptinae.
Opatrini
darkling beetles
Opatrini is a tribe of darkling beetles (Tenebrionidae) comprising approximately 281 genera and about 4,000 species, representing one of the most species-rich lineages within the family. The tribe was historically placed in subfamily Tenebrioninae but was transferred to the resurrected subfamily Blaptinae in 2021 based on phylogenetic analyses. The fossil genus Eupachypterus from Eocene Oise amber demonstrates that Opatrini-like morphology has persisted for over 50 million years. The tribe includes several subtribes, with molecular studies supporting the monophyly of Blapstinina and revealing complex relationships among geographically distributed genera.
Platynotini
Platynotini is a tribe of darkling beetles within the family Tenebrionidae, containing more than 70 genera distributed across multiple biogeographic regions including North and South America, the southern Palaearctic, the Afrotropical region, and the Indomalayan realm. The tribe is distinguished from other Blaptinae tribes by the presence of a stridulatory gula used for sound production. Recent molecular phylogenetic studies have strongly supported the monophyly of Platynotini. Members of this tribe exhibit considerable morphological diversity, with some African species such as Anomalipus being heavily built and armored, adapted to dense bush-covered savanna habitats.
