Trogloderus
Trogloderus is a genus of psammophilic darkling beetles (Coleoptera: Tenebrionidae) endemic to dunes and sandy habitats in the western United States. The genus comprises ten described species, including six new species described in 2019 from desert regions across the Intermountain Region. Molecular phylogenetic analysis dates the most recent common ancestor to 5.2 million years ago, with speciation driven by geographic features of the Lahontan Trough, Bouse Embayment, and Kaibab Plateau during the mid-Pleistocene.
