The Chacoan fairy armadillo is a small armadillo that lives underground in sandy soil. It has reduced eyes and ears and digging foreclaws.
Its eyes and ears are small, its body is covered by a shell, and its forefeet have large claws for digging.
In Bolivia’s Izozog region, two live individuals were observed over four years. One female appeared at a research camp at about 22:00, moved quickly while sniffing along the ground, and made shallow excavations in search of food. She buried half her body when observers approached.
In June 2018, a local rancher reported one animal emerging near the Pilcomayo River shore near Cutaiqui in Tarija, southern Bolivia, at about 02:00. The discovery site lay in an old river channel with deep, well-drained sandy soil and sparse, low thorn woodland.
An extinction-risk assessment has not been added yet.
