Clingmans Dome Ground Beetle (Trechus novaculosus)
This species, described in 1962, was restricted to its type locality, Clingmans Dome in Sevier County in Tennessee, USA. [1]
The species is thought to have also occurred in North carolina, however, I’m unable to find any additional information.
The species is thought to be extinct now.
