From the IUCN Red List Species Account:

 

Range Description

This species is known from one threat-defined location of La Joya and surrounding areas in central-western Veracruz, Mexico, at 1,200 m asl. Its extent of occurrence (EOO) and area of occupancy (AOO) is 72 km2.

Habitat and Ecology

The species lives in bromeliads in pine-oak and cloud forests. It breeds by direct development.

Population

It was abundant in its tiny range, but severe habitat degradation has occurred and the species has not been as easy to find during recent attempts. Studies performed by Eduardo Pineda and his group at INECOL searched for this species on several occasions. They found 41 individuals with 400 person hours of field sampling. These individuals were found at 3 localities near the type locality, however some of these individuals have  morphological differences which indicate they might represent different species. Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.

Population Trend

decreasing

Major Threats

All areas surrounding La Joya are highly disturbed by extensive deforestation (from logging, urbanization and agriculture, including the use of slash and burn methods (P. Arias-Caballero pers. comm. August 2015) and mining). Between 2003 and 2004 the area of forest habitat available for this species was halved due to the expansion of mining activities; the remaining available habitat was only about 15 ha in 2004.

Conservation Actions

Conservation Actions
This species is not known from any protected areas, however, it is protected by Mexican law under the "Special Protection" category (Pr).

Conservation Needed
Maintenance and protection of the La Joya forest is urgently needed.

Red List Status

Critically Endangered (CR)

Rationale

Listed as Critically Endangered because its extent of occurrence (EOO) is 72 kmĀ², all individuals are known from one threat-defined location, and there is a continuing decline in the extent and quality of its habitat at La Joya.

Taxonomic Notes

There is continuing uncertainty as to the taxonomic status of this form (D. Wake and G. Parra-Olea pers. comm.).
