Rana johni

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 known only from south-eastern San Luis Potosí and eastern Hidalgo, Mexico, at low to moderate elevations.

Habitat and Ecology

It is found in low and moderate elevation montane forest, and is usually found in or near river systems, and breeds in rivers.

Population

It is a rare species.

Population Trend

decreasing

Major Threats

The major threat to this species is habitat loss and disturbance due to clear-cutting of the forest, which could in turn lead to the disappearance or drying out of permanent water bodies.

Conservation Actions

It is not known from any protected areas, and there is a need for immediate protection of the montane forest habitat of this species. A survey of the San Luis Potosí localities is needed to establish the population status of the species in that region. This species is protected by Mexican law under the "Special Protection" category (Pr).

Red List Status

Endangered (EN)

Rationale

Listed as Endangered, in view of its Extent of Occurrence of less than 5,000km2 and Area of Occupancy of less than 500km2, with all individuals in fewer than five locations, and a continuing decline in the extent and quality of its habitat.
