Study Finds Significant Northern Pygmy Slow Loris Population in China

Research from Guangxi Normal University has identified a substantial population of northern pygmy slow lorises (Xanthonycticebus intermedius) in Guangxi province, China. Between June and October 2025, researchers conducted nighttime spotlight surveys and recorded 98 individuals, effectively doubling the species' known presence in the country. These findings, published in the journal Integrative Zoology on September 22, 2026, are significant as the animal was previously thought to reside almost entirely in Vietnam and Laos.

Recognized as a distinct species only in 2023, the northern pygmy slow loris is distinguished from its southern relative, the southern pygmy slow loris (Xanthonycticebus pygmaeus), by its plumper build and flatter nose. The species currently faces pressure from habitat loss and hunting for traditional medicine and the wildlife trade. This discovery suggests that the rugged karst forests of Guangxi may harbor a previously overlooked population, offering new insights into where these primates live and what they need to survive.

The study spanned six different areas across Guangxi, with the team covering nearly 286 kilometers (178 miles). Lorises were spotted in four of these locations, including a high of 37 individuals in Longzhou. Researchers also noted high encounter rates in Ningming and Pingxiang, highlighting the presence of these typically elusive animals. Notably, 79 of the 98 lorises were located outside of protected zones, which presents a specific challenge for conservationists working against habitat degradation and illegal trade.

Beyond the increase in recorded numbers, the discovery sheds light on a unique animal and its place in the local ecosystem. Conservationists are calling for better habitat protection and stronger measures against wildlife trafficking, as these lorises are often caught opportunistically by hunters. Because they are nocturnal and elusive, they frequently go unnoticed in broader studies, making targeted research essential for their long-term protection.

The research team expects these findings to encourage further investigation into the northern pygmy slow loris and its environment. Experts in the field have noted the importance of recognizing and studying such overlooked species. As work continues, the data may lead to more effective protective measures, helping the population remain stable within its natural habitat and supporting the broader biodiversity of the region.
