Discovered as recently as 1980 (1), the Chacoan naked-tailed armadillo is the smallest of the four species of naked-tailed armadillo (3). Like other members of the family, the upper surface of this species’ head, body and limbs is armoured with thick bony plates, separated by flexible bands of skin. The Chacoan naked-tailed armadillo’s head is wide, tapering to a short, broad snout (3), and bears small ears with distinctive fleshy borders (4). The upperparts are brown or blackish, while in contrast, the underparts are a dull, yellowish-grey. The claws of the forefeet are long and powerful, particularly the middle claw, which is especially large, and shaped like a sickle. As its name suggests, the tail of this species is not well-armoured, and only possesses a sparse covering of small, thin plates (3).
