Lepilemur ankaranensis

Animalia, Lepilemuridae, EN

Lepilemur ankaranensis is one of the smaller sportive lemurs, with an average head- body length of 22 cm, a tail length of 27 cm, a total length of 49 cm, and a body weight of 750–790 g (Louis et al., 2006b). The description that follows is based on specimens that had previously been assigned to Lepilemur septentrionalis, a species that evidently has a much more restricted range than previously believed (Ravoarimanana et al., 2004; Rumpler, 2004). The overall color is a light grayish-brown above with a gray underside. There is often a dark median stripe extending from the crown of the head along the spine, as well as brownish tinges in the shoulder region. The tail is pale brown, darkening towards the tip. The ears are less prominent than those of other Lepilemur species. This species might be confused in the field with Phaner or Cheirogaleus if only a fleeting glimpse of the animal is obtained, and also with Avahi even under good conditions. \([\dots]\) https://lemursofmadagascar.com
