Reason: This species is only known from one area where it is extremely isolated and the entire range of this species was burned over by a catastrophic wildfire in 2011. It is unknown if the species is still extent or not. Due to only being known from one occurrence this species also has a very small Extent of Occurrence and Area of Occupancy potentially as low as 1km2. As a result, this species is currently assessed as S1 in New Mexico. However, a reassesment should be done if more information becomes available.
