Genus Guides

Amphidorini is a tribe of darkling beetles (Tenebrionidae) comprising six , all native to North America. The tribe was reclassified in 2021 from Tenebrioninae to the resurrected 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.

Taxonomic history

In 2021, Kamiński et al. moved Amphidorini and six other tribes from Tenebrioninae into the newly resurrected Blaptinae. This transfer encompassed 281 and approximately 4000 , representing about 50% of former Tenebrioninae diversity. Bouchard et al. (2021) adopted this classification. In 2022, Johnston et al. removed Nycterinus from Amphidorini, placing it in incertae sedis within Tenebrioninae.

Genera composition

The tribe contains six : Eleodes (1829), Eleodimorpha (1909), Embaphion (1824), Lariversius (1947), Neobaphion (1925), and Trogloderus (1879). All are restricted to North America except Eleodes, which also occurs in the Neotropics.
