In a remarkable twist of fate, scientists have rediscovered a rare species of snake in a southeastern China mountain forest. On a hike in 2018, a team of researchers stumbled upon a creature they thought they had lost track of—Plagiopholis styani, or the Chinese Mountain Snake. This species, first identified in 1899, had long been elusive and rarely observed. The snake was found in the Wuyishan Mountains in Fujian Province, China, as part of a biodiversity survey led by scientists eager to document reptile diversity in the region.
The study, which was published on July 23 in the Biodiversity Data Journal, reveals that this rare reptile species had been hiding in plain sight. The creature had concealed itself under a pile of dead leaves, only emerging when disturbed by the researchers. Their encounter not only led to the rediscovery of a species but also ignited fresh discussions about the diversity and conservation status of reptiles in the mountainous regions of southern China.
The Rediscovery of Plagiopholis Styani
The Chinese Mountain Snake was first documented over a century ago in Fujian Province, but sightings have been few and far between. The researchers were on a typical reptile survey when they came across the snake hiding under a blanket of dead leaves. Despite its rare appearance, the snake was relatively easy to capture—slow-moving and non-threatening. Upon closer examination, the researchers realized they were encountering Plagiopholis styani, a species that had not been documented in the area in over a century.
This species belongs to a group of snakes that are typically secretive, difficult to spot, and rarely studied. Their elusive nature means that many of these snakes, although widespread across Asia, remain largely unknown to science. The recent finding adds an intriguing layer to our understanding of the region’s reptile biodiversity.

Rare Snake Species Revealed by DNA Analysis
Researchers have uncovered new insights about the distribution of the Chinese Mountain Snake through DNA analysis. While the species was once thought to be widespread across southern China, the newfound specimen revealed that it may be more localized than previously believed. The DNA data suggests that Plagiopholis styani is likely confined to Fujian and nearby provinces, challenging old assumptions about its distribution range. This breakthrough also suggests that some snakes previously identified as Chinese Mountain Snakes may, in fact, belong to an entirely different, yet undiscovered species.
This discovery raises questions about the ecological history of the region and the possible existence of other unknown species hiding in the forested mountains. Understanding the true range of the snake will be essential for future conservation efforts and will help clarify its role in the local ecosystem.
A Glimpse into the Elusive World of the Chinese Mountain Snake
The Chinese Mountain Snake is an incredibly secretive creature, which is why sightings are so rare. Described as having a greyish-brown body with small black spots, the snake has a rather unassuming appearance. It grows to about 16 inches in length and has a short body and tail, which allows it to blend seamlessly with its environment. In its natural habitat—leaf-littered hillsides and shaded forests—the snake is well adapted for hiding.
When disturbed, the snake tends to emerge slowly from its shelter and slither through the underbrush, as it did when researchers encountered it. The researchers reported that the snake’s calm demeanor made it easy to catch, offering an opportunity to study it closely. The detailed features, including its distinctive scale pattern, helped the team confirm their initial identification.
