From the IUCN Red List Species Account:


Range Description

This species is known from the Sierra Madre Oriental, in extreme east-central Hidalgo, up to the border with the states of Puebla and Tlaxcala, Mexico. It has been recorded at 2,250-3,050m asl. It probably occurs more widely than current records suggest, especially in areas between known sites.

Habitat and Ecology

It occurs in pine and fir forests and montane meadows, and is commonly found close to streams, in which it breeds.


This is thought to be a rare species. Surveys conducted in 2001 within the species' range collected only a single specimen.

Population Trend


Major Threats

The main threat to this species is habitat loss and degradation due to the activities of smallholder farmers, logging, and human settlement. Chytridiomycosis may also be a threat, as it is a high-elevation stream-breeding amphibian, and declines due to the disease have already been detected amongst other species of this genus.

Conservation Actions

The range of this species includes Parque Nacional El Chico, although this was logged in the last 10-15 years and is subject to human settlement. Expanded and strengthened protection of the high-elevation pine and fir forests in the Sierra Madre Oriental of eastern Hidalgo is necessary, and an extensive survey to establish the current population status of this species (and the threat posed by chytrid) is required. This species is listed as "Threatened" (Amenazada) by the Mexican government.

Red List Status

Endangered (EN)


Listed as Endangered because its Extent of Occurrence is less than 5,000km2 and its Area of Occupancy is less than 500km2, its distribution is severely fragmented, and there is a continuing decline in the extent and quality of its montane forest habitat.

Taxonomic Notes

This species was previously included in the genus Hyla but has recently been moved to the genus Plectrohyla (Faivovich et al. 2005).
