The fire- tailed jumper monkey ( Plecturocebus miltoni , Syn . : Callicebus miltoni ) is a small primate species from the subfamily of the jumper monkeys within the family of the sakia monkeys (Pitheciidae) that was only described in 2014 . The species was named after the nestor of Brazilian primatology Milton Thiago de Mello .
features
The fire-tailed spring monkey is a species from the Plecturocebus moloch group. It has an agouti- gray coat color on the top of the head, neck, back and on the outside of the arms and legs. In contrast, there is the light gray to whitish tinted hair of the vibrissae , hands and feet and a narrow forehead strip directly above the eyes. Throat, cheeks, belly side and tail are distinctively reddish to orange in color. The fire-tailed spring monkey can be distinguished from other species of the Plecturocebus moloch group in neighboring regions mainly by its striking tail color. The dark gray jumper monkey ( Plecturocebus cinerascens ) found to the east of its distribution area is dark gray in color, the Prince Bernhard jumper monkey ( Plecturocebus bernhardi ) found west of the Rio Roosevelt has a gray-brown fur, a lighter orange-colored throat and a gray-brown tail with a white tip.
Distribution and habitat and behavior
The fire-tailed spring monkey occurs in western Brazil in the northwest of Mato Grosso and in the southeast of the state of Amazonas in the area between Rio Aripuanã and Rio Roosevelt on both sides of the Río Guariba and thus has the same range as the Aripuanã marmoset ( Mico intermedius ). The holotype was caught on the west bank of the Rio Roosevelt, the five paratypes near the confluence of the Río Guariba with the Rio Aripuanã.
The habitat in which the holotype was caught is a moist, evergreen rainforest with tall trees mainly consisting of rubber trees ( Hevea brasiliensis ), Hymenaea intermedia , Peltogyne catingue , Apuleia molaris , Copaifera spp., Dialium guianense , Diplotropis racemosa , tonka trees ( Dipteryx odorata ), Ormosia nobilis and Parkia sp. consists. Smaller tree species (up to 15 m) are Eschweilera wachenheimii , Geissospermum urceolatum , Tachigali alba and the palm species Oenocarpus bataua , Sochratea exorrhiza and Euterpe precatoria . The upper shrub layer is made up of crushed shrubs ( Psychotria ) and Miconia sp. characterized, in the lower (0.1 to 0.5 m) grow Olyra cf. latifolia , Selaginella conduplicata and Calthea altissima .
In field studies , the fire-tailed spring monkey was seen in small groups of two to five individuals, mostly in the middle to higher tree regions. Two groups of four to five animals in the vicinity of the Rio Roosevelt comprised old and young animals and ate the fruits of ant trees ( Cecropia ), Inga sp. and Theobroma speciosum . However, no information can currently be given about the exact group size. Like other jumping monkeys, the animals mark their territory with morning duets.
