Plump, fuzzy and venomous, with wide eyes, a button nose and sharp teeth, northern pygmy slow lorises were thought to reside almost exclusively in Vietnam and Laos. However, new research has documented 98 of the endangered primates in Guangxi, China, in what could be the country’s largest known population of the species. The finding, published in the journal Integrative Zoology by researchers at Guangxi Normal University, expands the known range of the nocturnal primate and suggests that a substantial population may have gone undetected in Guangxi’s rugged karst forests. The species, Xanthonycticebus intermedius, was previously thought to number just over 100 individuals in China, primarily in Yunnan province. Its known range also extends south into northern Vietnam, reaching as far as Hai Van Pass. Anna Nekaris, a professor of ecology, conservation and environment at Anglia Ruskin University in the U.K. and founder of the Little Fireface Project that focuses on lorises, said she’s excited by the discovery and hopes it will inspire research on this understudied species. “A lot of these nocturnal animals — they’re so little known in the wild, they’re so little researched, that when you actually do go look for them and you find them, that’s incredible,” Nekaris said. Pygmy slow lorises are native to Southeast Asia. Xanthonyticebus intermedius, the northern pygmy slow loris, was only recognized as a distinct species in 2023 after genetic and morphological research separated it from its close relative, the southern pygmy slow loris (Xanthonycticebus pygmaeus). The northern pygmy slow loris, was…This article was originally published on Mongabay
