Rhinopithecus strykeriis is a member of primates, Cercopithecidae, Colobinae and Rhinopithecus. It not only has upturned nostrils as the other snub-nosed monkeys do, but also the unique hair colors, all black except the ears, the mandibular beard and the perineum that are covered with white hair. Geissmann first reported the existence of this species in 2010 when it was believed that the species was located only on the eastern side of the upper Maw Rive in northeastern Kachin state, Myanmar, with a population size estimated to be 260~330 individuals. Its population is estimated to decrease rapidly, thus it is recognized as critically endangered by the IUCN. However, due to the location that the R. strykeri population was discovered is not far from the China-Myanmar border, the possibility of other populations may exist in China has drawn much attention. In 2011, Liu Pu, a forest guard at Gaoligong Mountain National Nature Reserve (GNNR), found and took photos of a group of snub-nosed monkeys in Mapo Township of Lushui County, which were later identified by Long Yongcheng as R. strykery. The primate group was then named “Rhinopithecus strykeriis”, according to the convention of naming the animal after the place it was found. After the discovery of Rhinopithecus strykeriis, the Reserve took emergency actions on its protection and research. During 2012-2013, the Nujiang Management Bureau, the Lushui Management and Protection Bureau of the Gaoligong Mountain National Nature Reserve and the Institute of Eastern Himalaya Biodiversity Research of Dali University jointly investigated the Rhinopithecus strykeriis distribution and population status in China and the Rhinopithecus strykeriis distribution was preliminarily mastered. In order to confirm that besides Mapo Township of Nujiang Prefecture (western slope), there also distributed Rhinopithecus strykeriis on the eastern slope of Mountain Gaoligong, Lushui Management and Protection Bureau of Gaoligong Mountain National Nature Reserve conducted a field survey in Luoma on the eastern slope, the southern bank of Tingming River and other places within Lushui Country border from the year of 2015 to 2016. The one-year field survey found that Rhinopithecus strykeriis had a larger number and broader range, and was more susceptible to human disturbance. From 2013 to 2016, two adult Rhinopithecus strykeriis were saved owing to extensive publicity. Therefore, it is necessary to conduct the field work to further strengthen researches on Rhinopithecus strykeriis feeding habits to optimize the food recipe for the caged Rhinopithecus strykeriis, providing scientific support for effective in situ and ex-situ conservation.
