This tribe contains the most fossorial of all armadillos. The ears are small and eyes tiny. Head shield is reduced to a thin flexible plate which is separated from the rounded rump plate. The sides of the body and ventral region is covered with long, thick whitish hair. Forefoot possesses five digits with disproportionately large claws - the species is adapted for "fast digging" in soft soils as opposed to "power digging" in hard substrates.
