AMPHIBIAWEB
Rana sierramadrensis

Subgenus: Zweifelia
family: Ranidae
Taxonomic Notes: This species was placed in the genus Lithobates by Frost et al. (2006). However, Yuan et al. (2016, Systematic Biology, doi: 10.1093/sysbio/syw055) showed that this action created problems of paraphyly in other genera. Yuan et al. (2016) recognized subgenera within Rana for the major traditional species groups, with Lithobates used as the subgenus for the Rana palmipes group. AmphibiaWeb recommends the optional use of these subgenera to refer to these major species groups, with names written as Rana (Aquarana) catesbeiana, for example.

From the IUCN Red List Species Account:

 

Range Description

This species is widespread through the Sierra Madre del Sur of Guerrero and Oaxaca, Mexico.

Habitat and Ecology

This species inhabits conifer forests at intermediate elevations. It breeds in streams.

Population

There are many healthy populations of this species along its range although it is reportedly rare in some parts.

Population Trend

decreasing

Major Threats

Logging is probably a threat to this species. Tadpoles have been found in southern Mexico with loss of keratinized mouthparts, which suggests that chytridiomycosis might be a threat.

Conservation Actions

The range of this species does not include any protected areas, and there is a need for improved protection and maintenance of forest habitats in the Sierra Madre del Sur. This species is protected by Mexican law under the "Special Protection" category (Pr).

Red List Status

Vulnerable (VU)

Rationale

Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat in Guerrero and Oaxaca, Mexico.
