Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2014
Date Assessed: 2013-10-03
Assessor(s): Noss, A., Superina, M. & Abba, A.M.
Reviewer(s): Loughry, J.
Facilitator/Compiler(s): Superina, M.
Justification:
Tolypeutes matacus is listed as Near Threatened because this species is probably in significant decline (albeit at a rate of less than 30% over ten years) because of widespread habitat loss through much of its range, and because of exploitation for food, thus making the species close to qualifying for Vulnerable under criterion A2cd.
History:
2010 Near Threatened
2006 Near Threatened (IUCN 2006)
2006 Near Threatened
1996 Lower Risk/near threatened (Baillie and Groombridge 1996)

Geographic Range [top]

Range Description: Tolypeutes matacus is found from eastern Bolivia and south-western Brazil, south through the Gran Chaco of Paraguay, to Argentina (San Luis province). The species was once present in southern Buenos Aires Province (Yepes 1928) but recent surveys suggest that it is now extinct in this area (Abba and Vizcaíno 2008, 2011; Abba et al. 2012). The reason for its disappearance from Buenos Aires is unknown, but may be related to climate. It ranges from sea level up to 800 m Asl (Argentina).
Countries:
Native:
Argentina (Catamarca, Chaco, Córdoba, Formosa, La Rioja, Mendoza, Salta, San Juan, San Luis, Santa Fé, Santiago del Estero, Tucumán); Bolivia, Plurinational States of; Brazil (Mato Grosso, Mato Grosso do Sul); Paraguay

Population [top]

Population: Tolypeutes matacus is common in most xeric parts of the Paraguayan Chaco (Redford and Eisenberg 1992, Meritt 2008). It was recorded at densities of 1.9 animals per km² in the Bolivian Chaco (Cuéllar 2002). The wild population is decreasing, mainly due to intense hunting and habitat loss.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This armadillo, which can roll into a ball when threatened, is found in areas of dry vegetation within the Chaco (Bolkovic et al. 1995). It usually does not dig burrows but rather uses abandoned burrows of other species or hides in dense vegetation. It has a slow reproductive rate; the females give birth to a single young per litter and per year.
Systems: Terrestrial

Use and Trade [top]

Use and Trade: This armadillo is hunted for food and used as a pet species, both within its range and in other countries. It is also used to make handicrafts.

Threats [top]

Major Threat(s): Tolypeutes matacus is threatened by hunting for food; as it is not fossorial, it is easier to hunt than other armadillo species. It is also threatened by habitat destruction through conversion of suitable habitat to cultivated land; however, it is able to adapt to low levels of agricultural disturbance. This species is exported to zoos and for pet trade, and there is a high mortality of individuals during this export process.

Conservation Actions [top]

Conservation Actions: Tolypeutes matacus has been recorded from a number of protected areas. There is a captive population in North American zoos.
