Meet the world’s newest monkey, the white-cheeked macaque – or Macaca
leucogenys - which has just been discovered in the Tibetan state of
Modog.
It is distinguishable from the other four macaque species by its rounded glans penis and a dark, hairy scrotum. The other macaque species have spear-shaped glans penis’ and white scrotums.
The newest addition to the macque family also differs from the others in that it has thick, long hair around its neck.
The macaque forages in a wide range of habitats, including tropical, broad-leaf and conifer forests, according to the researchers who identified it.
The state of Modog is tremendously varied, taking in low-lying grasslands and alpine meadows, as well as tropical and evergreen forests, while the region is isolation. As a result, the discovery of a new type of macaque in the state has raised hopes that the area could be host to other undiscovered species.
“The forest in Modog is like a nature library, and we know very little about it. Discovery of the new macaque species suggests that there may be some species that still remain undiscovered in this area,” Chao Zhao, a researcher at Dail University’s Institute of Eastern-Himalaya Biodiversity Research, who worked on the study, told New Scientist magazine.
His team took 738 photographs of macaques by set up camera traps in four Tibetan gorges and compared them with photos of known species. It was then they discovered a species with a different form and structure – or morphology - to the others.
“Our photos clearly showed some morphological differences between the new species and other known species,” said co-author Peng-Fei Fan, also at Dali University.
The study has been published in the American Journal of Primatology.
Paul Garber, editor of the journal, is also hopeful that further new species can be identified in Modog, for political as well as environmental reasons.

“It is an area where there’s been very little scientific exploration, partly because of political conflicts,” Mr Garber said.
The research noted the newly-discovered white-cheeked macaques are already under threat, from hunting carried out by local tribes as well as construction planned for the region.
“Construction of hydropower stations would result in destroying and flooding extensive areas of forests along the rivers, the potential habitat for white-cheeked macaques.,” the report said.
“The immigration of a large number of people into the area to construct the hydropower stations also will result in an increase in the bushmeat trade, deforestation, new roads and the construction of housing for workers – all of which will have a negative impact on white-cheeked macaque conservation,” the report added.
