Avahi betsileo Andriantompohavana et al., 2007

Avahi betsileo has a head-body length of 26–31.1 cm, a tail of 28.3–34.4 cm, a total length of 48–58.9 cm, and a weight of 900–1,200 g (Andriantompohavana et al., 2007; Lei et al., 2008). It differs significantly from other eastern woolly lemurs in having primarily light reddish-brown pelage on the upper body and on the dorsal surface of the extremities, with an underside that is dark gray towards the midline and diffusing to a light gray ventrolaterally. The tail is mainly reddish-brown and darker on the dorsal surface than on the ventral portion, which is a lighter reddish-blonde. There is a distinct facial mask, with grayish pelage under the mandible and diffuse, cream-colored eyebrow markings. The fur is thicker on the head than in other eastern Avahi, giving it a more rounded or oval-like apprearance (Andriantompohavana et al., 2007).
