From the IUCN Red List Species Account:

 

Range Description

This species is only known from one threat-defined location of the northern slopes of the Sierra de Juarez, northern Oaxaca, Mexico, between 730-1,500 m asl (Lamoreux et al. 2015). Its extent of occurrence (EOO) and area of occupancy are 93 km2.

Habitat and Ecology

It lives in cloud forest, where it is terrestrial and fossorial, and does not survive in seriously disturbed habitats. It breeds by direct development and is not dependent upon water.

Population

It is very poorly known and only a few specimens have ever been recorded, despite much fieldwork having been carried out in its range. However, due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.

Population Trend

decreasing

Major Threats

The main threats are habitat loss due to logging, human settlement and expanding agriculture.

Conservation Actions

Conservation Actions
It does not occur in any protected areas.

Conservation Needed
Habitat protection a priority to ensure the long-term survival of this species.

Research Needed
Further survey work is needed to determine its current population and taxonomic status.

Red List Status

Critically Endangered (CR)

Rationale

Listed as Critically Endangered because its extent of occurrence (EOO) is 93 km2, it occurs in one threat-defined location and there is continuing decline in the extent and quality of its habitat in northern Oaxaca, Mexico.

Taxonomic Notes

There is a question as to whether both Pseudoeurycea orchileucos and Pseudoeurycea orchimelas are distinct, valid species.
