From the IUCN Red List Species Account:


Range Description

This species is known only from two locations in northern Jitotol, north-central Chiapas, Mexico, at 1,200-1,550m asl. It is presumed to occur between the known localities in appropriate habitat, but further data are required.

Habitat and Ecology

It inhabits cloud forest, and seems to require microclimates with very high humidity. It has been found at roadsides, but it is not known whether or not it can live in disturbed habitats. It is terrestrial and reproduces by direct development.


It is likely to be very rare; only 3-4 specimens of this species are known and recent surveys have failed to record any specimens.

Population Trend


Major Threats

The major threat is habitat loss due to expanding agriculture and human settlements, and also logging.

Conservation Actions

It has not been recorded from any protected areas, and there is therefore an urgent need for the protection of the cloud forest habitat of this species. Survey work is necessary to determine its current population status.

Red List Status

Endangered (EN)


Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat in Chiapas, Mexico.
