From the IUCN Red List Species Account:


Range Description

This species is known only from north-central Oaxaca, southern Mexico.

Habitat and Ecology

It is a species of pine and pine-oak forests at high elevations. It is terrestrial, found beneath logs and rocks. The species is presumed to reproduce by direct development.


It was known to be common to very common 30 years ago, but is now rarely found (D. Wake pers. comm., 2005).

Population Trend


Major Threats

Habitat loss does not appear to be at a scale large enough to explain observed declines.

Conservation Actions

This species is not known from any protected areas. Research is needed to determine the reason for the apparent population declines in suitable habitat.

Red List Status

Vulnerable (VU)


Listed as Vulnerable because a large, recent population decline has been observed that is believed to be greater than 30% and which is not understood.

Taxonomic Notes

Pseudoeurycea boneti has recently been resurrected from synonymy with P. bellii (Parra-Olea et al. 2005).
