Kingdom Phylum Class Order Family
Animalia Chordata Mammalia Cingulata Chlamyphoridae

Scientific Name: Calyptophractus retusus (Burmeister, 1863)
Common Name(s):
English Greater Fairy Armadillo, Burmeister's Armadillo, Chacoan Fairy Armadillo, Greater Pichi Ciego
Spanish Pichiciego Mayor
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). Classification in the genus Calyptophractus is supported by molecular data showing substantial divergence from Chlamyphorus truncatus (Delsuc et al. 2012).

Two subspecies have been described (Yepes 1939).

Threats [top]

Major Threat(s): Calyptophractus retusus is under threat from 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: This small armadillo 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).
