From the IUCN Red List Species Account:

 

Range Description

This species occurs in three sites in Veracruz, Mexico: one at the peak of Cerro Chicahuaxtla, Cuatlapan at 1,600 m asl, another near this site, and at 1,200-1,300 m asl on Volcán San Martín. It is likely that the taxon consists of two separate species, one in each region, with Pseudoeurycea nigromaculata sensu stricto likely to be the subpopulation at Cerro Chicahuaxtla. Its extent of occurrence (EOO) is 4,284 km2.

Habitat and Ecology

This species is arboreal and is found in montane tropical forest (cloud forest) living in bromeliads, an unusual habitat for a salamander in this genus. It reproduces by direct development.

Population

Once relatively common, it is now very rare and only a single specimen was recorded at Cerro Chicahuaxtla in 2007 after not having been seen since the mid-1980s. Between 2010 and 2012, field studies conducted by Eduardo Pineda and his group at INECOL, found 10 specimens in two localities with 650 person hours of sampling effort. Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.

Population Trend

decreasing

Major Threats

Most of the habitat of this species has disappeared or has been severely degraded as a result of logging, agriculture, and expanding human settlements.

Conservation Actions

Conservation Actions
This species has not been recorded in any protected areas. It is protected by Mexican law under the "Special Protection" category (Pr).

Conservation Needed
Protection of the remaining habitat at the known sites is urgently needed. 

Research Needed
Distribution surveys at all sites are required, as is taxonomy research to clarify the identity of all subpopulations.

Red List Status

Endangered (EN)

Rationale

Listed as Endangered because its extent of occurrence (EOO) is 4,284 km2, it occurs in two threat-defined locations, and there is a continuing decline in the extent and quality of its habitat in Veracruz, Mexico.

Taxonomic Notes

It is likely that this form consists of two separate species (G. Parra-Olea and D. Wake pers. comm.).
