The South American foxes (Lycalopex), commonly called raposa in Portuguese, or zorro in Spanish, are a genus from South America of the subfamily Caninae. Despite their name, they are not true foxes, but are a unique canid genus more closely related to wolves and jackals than to true foxes; some of them resemble foxes due to convergent evolution. The South American gray fox, Lycalopex griseus, is the most common species, and is known for its large ears and a highly marketable, russet-fringed pelt.
The second-oldest known fossils belonging to the genus were discovered in Chile, and date from 2.0 to 2.5 million years ago, in the mid- to late Pliocene. [4] The Vorohué Formation of Argentina has provided older fossils, dating to the Uquian to Ensenadan (Late Pliocene). [5]
The common English word "zorro" is a loan word from Spanish, with the word originally meaning "fox". Current usage lists Pseudalopex (literally: "false fox") as synonymous with Lycalopex ("wolf fox"), with the latter taking precedence. [1] [6] In 1895, Allen classified Pseudalopex as a subgenus of Canis , establishing the combination Canis (Pseudalopex), a name still used in the fossil record. [3]

In 1914, Oldfield Thomas established the genus Dusicyon , in which he included these zorros. They were later reclassified to Lycalopex (via Pseudalopex) by Langguth in 1975. [1]
The following phylogenetic tree shows the evolutionary relationships between the Lycalopex species, based on molecular analysis of mitochondrial DNA control region sequences. [7]

The zorros are hunted in Argentina for their durable, soft pelts. They are also often labelled 'lamb-killers'.[ citation needed ]
In his diary of his well-known 1952 traveling with the young Che Guevara, [8] Alberto Granado mentions talking with seasonal workers employed on vast sheep farms, who told him of a successful campaign by the ranch owners to exterminate the foxes who were preying on lambs. The ranchers offered a reward of one Argentinian peso for the body of a dead male fox and as much as five pesos for a female fox; to impoverished workers in the early 1950s, five pesos were a significant sum. Within a few years, foxes became virtually extinct in a large part of Argentina.
The Fuegian dog (Spanish : perro yagán, perro fueguino), also known as the Yaghan dog, was a domesticated form of the culpeo (Lycalopex culpaeus), [9] unlike other domesticated canids which were dogs and silver foxes. This means different canid species have been domesticated multiple times by humans independently.
Canidae is a biological family of dog-like carnivorans, colloquially referred to as dogs, and constitutes a clade. A member of this family is also called a canid. The family includes three subfamilies: the Caninae, and the extinct Borophaginae and Hesperocyoninae. The Caninae are known as canines, and include domestic dogs, wolves, coyotes, foxes, jackals and other species.
Vulpes is a genus of the sub-family Caninae. The members of this genus are colloquially referred to as true foxes, meaning they form a proper clade. The word "fox" occurs in the common names of all species of the genus, but also appears in the common names of other canid species. True foxes are distinguished from members of the genus Canis, such as domesticated dogs, wolves, jackals and coyotes, by their smaller size (5–11 kg), longer, bushier tail, and flatter skull. They have black, triangular markings between their eyes and nose, and the tip of their tail is often a different color from the rest of their pelt. The typical lifespan for this genus is between two and four years, but can reach up to a decade.
The culpeo, also known as Culpeo zorro, Andean zorro, Andean fox, Paramo wolf, Andean wolf, and colpeo fox, is a species of South American fox. Despite the name, it is not a true fox, but more closely related to wolves and jackals. Its appearance resembles that of foxes due to convergent evolution.
Dusicyon is an extinct genus of South American canids.
Urocyon is a genus of Canidae which includes the gray fox and the island fox. These two fox species are found in the Western Hemisphere. Whole genome sequencing indicates that Urocyon is the most basal genus of the living canids. Fossils of what is believed to be the ancestor of the gray fox, Urocyon progressus, have been found in Kansas and date to the Upper Pliocene, with some undescribed specimens dating even older.
The crab-eating fox, also known as the forest fox, wood fox, bushdog or maikong, is an extant species of medium-sized canid endemic to the central part of South America since at least the Pleistocene epoch. Like South American foxes, which are in the genus Lycalopex, it is not closely related to true foxes. Cerdocyon comes from the Greek words kerdo and kyon (dog) referring to the dog- and fox-like characteristics of this animal.
Darwin's fox or Darwin's zorro is an endangered canid from the genus Lycalopex. It is also known as the zorro chilote or zorro de Darwin in Spanish and lives in Nahuelbuta National Park, the Cordillera de Oncol, Cordillera Pelada in mainland Chile and Chiloé Island. This small, dark canine weighs 1.8 to 3.95 kg, has a head-and-body length of 48 to 59 cm and a tail that is 17.5 to 25.5 cm. Darwin's fox displays no key differences between male and female other than the fact that the male has a broader muzzle. Males display no territorial behavior and are not aggressive towards other males roaming around their territory.
The Sechuran fox, also called the Peruvian desert fox or the Sechuran zorro, is a small South American species of canid closely related to other South American "false" foxes or zorro. It gets its name for being found in the Sechura Desert in northwestern Peru.
The side-striped jackal is a canine native to Central and Southern Africa.
The Pampas fox, also known as grey pampean fox, Pampas zorro, Azara's fox, or Azara's zorro, is a medium-sized zorro, or "false" fox, native to the South American Pampas. Azara in some of its alternative common names is a reference to Spanish naturalist Félix de Azara.
The hoary fox or hoary zorro, also known as raposinha-do-campo in Brazil, is a species of zorro or "false" fox endemic to Brazil. Unlike many other foxes, it feeds primarily on small invertebrates such as insects.
The South American gray fox, also known as the Patagonian fox, the chilla or zorro gris, is a South American species of Lycalopex in the Canidae family, which includes dogs, wolves, jackals, coyotes and foxes, among other canids. It is endemic to the southern parts of Argentina and Chile, primarily Patagonia and Tierra Del Fuego.
Caninae is the only living subfamily within Canidae, alongside the extinct Borophaginae and Hesperocyoninae. They first appeared in North America, during the Oligocene around 35 million years ago, subsequently spreading to Asia and elsewhere in the Old World at the end of the Miocene, some 7 million to 8 million years ago.
The Labrador wolf is a subspecies of gray wolf native to Labrador and northern Quebec. It has been described as ranging in color from dark grizzly-gray to almost white, and of being closely related to the Newfoundland wolf. This wolf is recognized as a subspecies of Canis lupus in the taxonomic authority Mammal Species of the World (2005).
The Mackenzie River wolf or Mackenzie Arctic Wolf is a subspecies of gray wolf which is found in Canada's southern portion of Northwest Territories. Not much has been published on Canis lupus mackenzii but one of the most comprehensive studies was done in 1954 by W.A. Fuller, Wolf Control Operations, Southern Mackenzie District, Canada Wildlife Service Report. This wolf is recognized as a subspecies of Canis lupus in the taxonomic authority Mammal Species of the World (2005).
Dusicyon cultridens or Dusicyon patagonicus cultridens is an extinct canid species in the genus Dusicyon. However, the classification of this species is poorly researched and debatable. Some scientists place this species in the genera Canis and Lycalopex.
The Fuegian dog, or Yahgan dog, or Patagonian dog, is an extinct type of canid. Its ancestry is a matter of scientific debate, though traditionally it was thought to be bred and domesticated from the South American culpeo, also known as the culpeo fox.
Canini is a taxonomic rank which represents the dog-like tribe of the subfamily Caninae, and is sister to the fox-like tribe Vulpini. The Canini came into existence 9 million years ago. This group was first represented by Eucyon, mostly by Eucyon davisi that was spread widely across North America and is basal to the other members of the tribe. Its members are informally known as true dogs.
Cerdocyonina is an extant subtribe of the canines that is endemic to the Americas. Often described to be "fox-like" in appearance and behavior, they are more closely related to the wolf-like canids such as Canis than they are to the fox genus Vulpes. Its members are colloquially known as the South American canids and there are 10 extant species. They are sometimes referred to as South American foxes in the older literature, but the term zorro has been recommended by mammalogists to avoid confusion with the true foxes of the tribe Vulpini, which includes the genus Vulpes.
