Erythrocebus poliophaeus (Engl. Heuglin's Patas Monkey or Blue Nile Patas Monkey) is a primate of the genus Patas monkeys ( Erythrocebus ) within the family Cercopithecidae . The species wasfirst describedin 1862 by the German scientist Ludwig Reichenbach under the name "Der Graumähnige Patas" ( Cercopithecus poliophaeus ), but was later considered a synonym for Erythrocebus patas . It was only recognized as an independent species again in a publication by the Italian primatologist Spartaco Gippoliti in August 2017. To Erythrocebus poliophaeus the patas monkey populations are found, the east of the Blue Nile occur in eastern Sudan and in the far west of Ethiopia. Among other things, the species lives in Alatish National Park in north-west Ethiopia and in Dinder National Park in eastern Sudan.
features
Erythrocebus poliophaeus differs from the common hussar monkey mainly in its dark mane on the back, which is formed by dark gray to black, very long hair on the shoulders and the back of the neck. The mane extends to the upper arms. The face is black, the nose is also black in contrast to that of the white-nosed hussar monkey . The narrow black band that runs between the eyes and the base of the ears in the common hussar monkey and the white-nosed hussar monkey runs upwards on both sides of the forehead in Erythrocebus poliophaeus . The skull, back, sides and tail are reddish-brown. The abdomen, arms and legs, hands and feet and the whiskers are whitish. The gluteal calluses are pink in old animals, but yellowish to flesh-colored in young ones . The scrotum is blue-green in adult males and sky blue in younger ones. Reichenbach stated that the specimen he examined, which he received from Theodor von Heuglin , had a head body length of 26 " (= 66 cm) and a tail length of 24" (= 61 cm).
