Trogloderus nevadus
Trogloderus nevadus is a darkling beetle (Tenebrionidae) in the psammophilic genus Trogloderus. Originally described in 1943 from dunes around Pyramid Lake, Nevada. The species was briefly treated as a subspecies of T. costatus (1946) but restored to specific standing by Johnston in 2018. It is restricted to sandy dune habitats in the western United States.
