NatureServe Conservation Status
Rounded Global Status Rank: G2 - Imperiled
Reasons: Known from two mountain ranges in Nevada, the Sheep and Pintwater, in two counties Clark and Lincoln (16-20 occurrences estimated). All of the known occurrences are in very inaccessible areas of the Desert National Wildlife Refuge. This species hasn't been thoroughly surveyed and the last survey was conducted in 1993. This species occurs in crevices and on ledges of carbonate cliffs in remote areas that aren't easily accessed, and direct human threats probably aren't threats.
