Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA CINGULATA DASYPODIDAE

Scientific Name: Calyptophractus retusus
Species Authority: (Burmeister, 1863)
Common Name/s:
English Greater Fairy Armadillo, Burmeister's Armadillo, Chacoan Fairy Armadillo, Greater Pichi Ciego
Spanish Pichiciego Mayor
Synonym/s:
Burmeisteria retusa (Gray, 1856)
Chlamyphorus retusus (Burmeister, 1863)
Taxonomic Notes: Several synonyms are still commonly used for Calyptophractus Fitzinger, 1871 (Gardner 2007): Chlamyphorus Burmeister 1863; Burmeisteria Gray 1865 (this genus name was preoccupied by Burmeisteria Salter, 1865, a trilobite, and is therefore incorrect). Two subspecies have been described (Yepes 1939).

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2010
Date Assessed: 2009-12-10
Assessor/s: Abba, A.M. & Superina, M.
Reviewer/s: Meritt, D.A. & Cuellar, E.
Contributor/s: Meritt, D.A. & Cuellar, E.
Justification:
Calyptophractus retusus is classified as Data Deficient because virtually nothing is known about this species. It is known to be patchily distributed in appropriate microhabitats that are subject to ongoing habitat loss. The species is actively persecuted throughout its range, and a population reduction in the order of 20-25% over the past 10 years is not unlikely.
History:
2008 Near Threatened (IUCN 2008)
2008 Near Threatened
2006 Near Threatened (IUCN 2006)

1996 Vulnerable

Population [top]

Population: The population status of this small armadillo is not known.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: C. retusus is restricted to loose, sandy soils. It is patchily distributed and absent from areas with clay soils. It can be found in disturbed habitat, and may be encountered close to villages and other populated areas.
Systems: Terrestrial

Threats [top]

Major Threat(s): C. retusus is threatened by habitat loss in the Chaco region. It is persecuted because of traditional beliefs concerning the animal as an omen of disaster (Cuéllar 2001, Noss et al. 2008).

Conservation Actions [top]

Conservation Actions: It has been recorded in a number of protected areas in Bolivia (Cuéllar and Noss 2003), and Reserva Natural General Pizarro in Salta, Argentina (Regidor et al. 2005). In Paraguay, it is known from Defensores del Chaco National Park (Meritt 2008).
