Justification: The extent of occurrence of the species is extremely narrow (ca. 2,144 km²) and widely fragmented into two disjunct subpopulations, including five and four localities respectively. The area of occupancy of this species is ca. 610 km². The habitat is expected to decline in the future mostly due to goat over-pasturing and mining.

Geographic Range [top]

Range Description:	The extent of occurrence for this species is 2,144 km², in northern San Luis Potosí, Nuevo León and Tamaulipas. The range is divided into two separate subpopulations with an area of occupancy of ca. 580 and 32 km² respectively; five and four localities respectively have been recorded. The population estimate of less than 4,000 individuals is highly speculative.
