From the IUCN Red List Species Account:

 

Range Description

This species is known from the Sierra de Los Tuxtlas, southern Veracruz, Cerro Cangrejo (Oaxaca), and from the northern slopes of the Sierra de Juarez in the vicinity of Vista Hermosa, northern Oaxaca, Mexico. The type series was found between 915-1,372m asl (Darling and Smith 1954), but in recent surveys (2009-2010) it was found at 1,690 m asl in the Sierra de Juárez (S. Rovito pers. comm. Red List Assessment Workshop 2014). It is possible that this species could occur between known localities.The area of occupancy (AOO) is 197 km2 and the extent of occurrence (EOO) is 5,301 km2.

Habitat and Ecology

It is a terrestrial species that inhabits tropical rainforest and cloud forest habitats, and lives in moss mats. It can survive in somewhat disturbed forest but only that which provides plenty of shade. It reproduces by direct development.

Population

There is no information on its population status, possibly because it is very hard to find. The species has been recently found (2009 and 2010) in both Los Tuxtlas and the Sierra de Juárez, indicating that it persists in both areas.

Population Trend

unknown

Major Threats

The major threat to the species is habitat loss due to subsistence agriculture, logging, and human settlement.

Conservation Actions

Conservation Action
This species occurs in the Los Tuxtlas Biosphere Reserve in Veracruz. It is protected by Mexican law under the "Special Protection" category (Pr).

Conservation Needed
Habitat protection in Oaxaca is necessary, and further protection and restoration of habitat in Veracruz.

Research Needed
Further survey work is needed to determine the current species distribution, threats, and population size and trends.

Red List Status

Endangered (EN)

Rationale

Listed as Endangered because its area of occurrence (AOO) is 197 km2, it occurs in three threat-defined locations, and there is a continuing decline in the extent and quality of its habitat in Veracruz and Oaxaca.
