“…At present, IUCN categorizes genus Nycticebus into 5 species based on research with morphology as well as genetic and geographic morphometrical analysis [22]. Additionally, researchers are concerned about the reports of the presence of hybrids in overlapping habitats [10,20]. Phylogeny is not a topic of the current study, but we emphasize that our data show DNA similarity between Nycticebus bengalensis and Nycticebus coucang compared to the other three species.…”

The slow loris (Nycticebus) is a prosimian that is popular among exotic pet lovers. In Japan, many slow lorises have been imported illegally. Prosimians that have been confiscated in raids are protected in Japanese zoos, and the number of such animals has increased. In most cases, the country of origin remains unknown and even the species can be difficult to identify from the animal's physical appearance alone. We have attempted to resolve this problem by using DNA analysis. DNA samples of five species, consisting of the Pygmy slow loris (Nycticebus pygmaeus), Bengal slow loris (Nycticebus bengalensis), Sunda slow loris (Nycticebus coucang), Javan slow loris (Nycticebus javanicus), and Bornean slow loris (Nycticebus menagensis), were extracted, amplified, and the nucleotide sequences of mitochondrial 12S rRNA, 16S rRNA, and the cytochrome oxidase subunit 1(COI) regions were compared. Differences of nucleic acid sequences of representative individuals were demonstrated.

“…However, we could ask whether the polymorphism level of the Sichuan golden monkey is higher than that of related endangered species. Then, we compared data for Rhinopithecus roxellana data with that of 2 endangered primates: the bengal slow loris (Nycticebus bengalensis), sample size=21, and the pygmy slow loris (Nycticebus pygmaeus), sample size=119 (Pan et al 2007). For the HVR I of D-loop, θw and θπ for Nycticebus bengalensis are only 4.73 and 5.04, and for Nycticebus pygmaeus, they are only 1.50 and 0.746.…”

The Sichuan golden monkey (Rhinopithecus roxellana) is a famous and beautiful endangered primate. Owing to the dearth of samples and technical limitations, previous studies could not adequately assess the levels of genetic polymorphisms in the species. To evaluate the polymorphisms further, we sequenced the entire mitochondrial control regions (D-loop) of 35 individuals from the 3 major habitats: Minshan, Qinglin, and Shennongjia. We observed many polymorphisms and estimated that the effective population size of the current total population is less than ca. 480-2300, and the time to the most recent common ancestor is ca. 4000-62,700 years. Through comparisons, we showed that the population of Rhinopithecus roxellana has a relatively higher polymorphism level than that of other endangered primates.

“…In 1960, Dao recognized a third species, N. intermedius , intermediate between N. bengalensis and N. pygmaeus [Dao, 1960]. However, subsequent genetic analyses support it as a junior synonym of N. pygmaeus [Chen et al, 2006; Pan et al, 2007; Roos et al, 2007; Zhang et al, 1993] as do studies of morphology and pelage. It appears that the type specimen for N. pygmaeus was a subadult and that N. intermedius is an adult of the same taxon [Groves, 1971, 2004].…”

Vietnam has the highest number of primate taxa overall (24-27) and the highest number of globally threatened primate taxa (minimum 20) in Mainland Southeast Asia. Conservation management of these species depends in part on resolving taxonomic uncertainties, which remain numerous among the Asian primates. Recent research on genetic, morphological, and acoustic diversity in Vietnam's primates has clarified some of these uncertainties, although a number of significant classification issues still remain. Herein, we summarize and compare the major current taxonomic classifications of Vietnam's primates, discuss recent advances in the context of these taxonomies, and suggest key areas for additional research to best inform conservation efforts in a region crucial to global primate diversity. Among the most important next steps for the conservation of Vietnam's primates is a new consensus list of Asian primates that resolves current differences between major taxonomies, incorporates recent research advances, and recognizes units of diversity at scales below the species-level, whether termed populations, morphs, or subspecies. Priority should be placed on recognizing distinct populations, regardless of the species concept in use, in order to foster the evolutionary processes necessary for primate populations to cope with inevitable environmental changes. The long-term conservation of Vietnam's primates depends not only on an accepted and accurate taxonomy but also on funding for on-the-ground conservation activities, including training, and the continued dedication and leadership of Vietnamese researchers and managers.
