Justification: The known distribution of the species is extremely narrow (ca. 63 km²), severely fragmented, and only three (probably four) highly disjunct localities are known. The estimated number of individuals is critically low. The habitat is expected to decline in the future mostly due to cattle over-pasturing and agricultural development.

Geographic Range [top]

Range Description:	Restricted to a small area (ca. 63 km²) in Zacatecas, and present in very low population densities. Only three (probably four) highly disjunct localities are known. The population estimate of <1,000 individuals is highly speculative.
Countries:	Native: Mexico (Zacatecas)
