Принц Бернхардский тити: новый вид обезьян из Бразилии

Species of New World monkey

Prince Bernhard's titi monkey (Plecturocebus bernhardi), also called the zog zog monkey, is a species of titi monkey in the genus Plecturocebus, first described in 2002. It is named after Prince Bernhard of the Netherlands. They have varying coloration of gray, black, and agouti, with dark orange in certain regions. They are endemic to Brazil, found mostly in disturbed forest environments. While officially listed as least concern by the International Union for the Conservation of Nature (IUCN), they may, in fact, be at risk due to human caused deforestation.

The species is known to locals of the regions it inhabits as a zog zog or zogue zogue; Its English common name was selected in honor of Prince Bernhard of the Netherlands, who created the Order of the Golden Ark, an award equivalent to knighthood, presented each year to a group of conservationists. Van Roosmalen explained how the area where it is found is filled with undescribed species. In 2016, the genus was split into four new genera, with bernhardi ending up in the moloch group of the newly created genus Plecturocebus. Other members of that group include P. moloch, P. cinerascens, P. hoffmannsi, P. baptista, and P. brunneus.

C. bernhardi has dark orange sideburns, underparts, and inner limbs (of a more uniform shade than P. cinerascens). The upper regions of its body and head are grayish black, while on its back, these shades are mixed with brownish agouti or reddish brown. Its face is black, with white hairs around its nose and mouth. Its ears are also black, with whitish tufts. Its mostly black tail is contrasted by a white tip. Its hairs are long. Its grayish forehead and crown help distinguish it from P. brunneus, which is dark brown to black in these areas, while the white ear tufts and tail tip distinguish it from P. hoffmannsil and P. baptista. Its lack of black vibrissae (whiskers) sets it apart from P. dubius.

The Prince Bernhard's titi monkey is endemic to Brazil, specifically the states of Amazonas and Rondônia, and possibly Mato Grosso, although its presence in the third is uncertain, having possibly been sighted in Alta Floresta. It is found between the Madeira and Aripuanã rivers. The range of P. bernhardi overlaps with those of P. cinerascens and P. hoffmannsi at the headwaters of the Juruena, Aripuanã, and Roosevelt rivers. They occur in protected areas, including Ipixuna Indigenous Land.

In the early morning, before dawn, all the pairs in one area often begin to perform duet calls together.

The Prince Bernhard's titi monkey is of least concern by the International Union for Conservation of Nature (IUCN). The organization considered it to not be at risk due to its large range and lack of human impact on its habitat. They concluded that it has a stable population and no known threats.
