Rana brownorum

Subgenus: Pantherana
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 can be found in extreme southern New Mexico (Eddy County) and central and western Texas (north to Collin County), USA, south through eastern and southern Mexico through the Yucatán peninsula, Belize, northern Guatemala to northeastern Nicaragua. Introduced and well established at numerous sites along the lower Colorado River from the Mexican border north to Yuma, Arizona, and east 265km along the Gila River, to approximately Buckeye, Maricopa County, replacing native L. yavapaiensis (Platz et al. 1990, Clarkson and Rorabauch 1989, Platz 1991). A dichopatric population is present in western Chihuahua, Mexico (Smith and Chizar, 2003). It has a elevational range of sea level to 2,595m asl (western Chihuahua).

Habitat and Ecology

This species can be found along streams and rivers, springs, stock ponds, backwaters, canals, drainage ditches, and arroyo pools in grassland, shrubland, savannah, desert, and woodland areas; chiefly a stream dweller. It utilizes both temporary and permanent water. Eggs and larvae develop in flowing or non-flowing water (mostly the former).


This is one of the most widespread species of the genus. In some areas it has been detected that it can survive even under anthropogenic disturbed circumstances.

Population Trend


Major Threats

There appear to be no major threats to this species.

Conservation Actions

Further taxonomic studies are needed. This species occurs in several protected areas and is considered (probably incorrectly) under the Special Protection category by the Red Data Book of the Mexican Government.

Red List Status

Least Concern (LC)


Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining to qualify for listing in a more threatened category.

Taxonomic Notes

The taxonomic status of populations in the southern part of the range of this species is questionable and in need of further study; it is possible that multiple species are represented (Frost 1985, Campbell 1998, Lee 2000). We follow Campbell (1998) and Lee (1996) in considering L. brownorum to be a synonym of L. berlandieri. Smith and Chiszar (2003), consider the southwestern population of the species in Chihuahua, Mexico, to be dichopatric from the eastern population, and note that the western population probably represents a different taxon.
