Eulemur cinereiceps

Previously considered a subspecies of the brown lemur . In 2001, it was raised to the rank of a species, but some experts still consider it a subspecies of the totality of genetic and morphological data. ^[2] Also, molecular studies have shown that Eulemur albocollaris was the youngest synonym for Eulemur cinereiceps . ^{[3] [1] [4]}

Lemurs are medium in size. Moves on four limbs or jumps, using a long tail as a balance weight. They resemble representatives of a related species, Eulemur collaris , but are genetically different from it. The upper body of the male is gray-brown, the limbs and tail are darker. Lower body light gray. The head is also gray, with a dark crown. Females have a reddish-brown upper body, their belly is lighter and their limbs darker than in males. The cheeks and chin are covered with light long hair in males and reddish hair of medium length in females. Body length ranges from 39 to 40.5 cm, tail length from 50 to 55 cm, weight from 2 to 2.5 kg. ^[five]

It is found in the south-east of Madagascar , from the Manampatran River to the south to the ^{[2] [6]} .

Forms small groups of four to eleven individuals. It feeds mainly on fruit, leaves, flowers and mushrooms serve as a supplement to the diet. ^[7]

In 2005, the analysis of satellite images revealed that approximately 700 km ^{2 of the} natural habitat of these primates remained. ^[2] In addition to the destruction of relict forests, the threat of a population is illegal hunting. The species is on the list of the 25 most threatened primates. ^{[8] The} International Union for Conservation of Nature granted him the conservation status of “Endangered”. ^[9]
