Researchers have identified a new species of pitviper, named Trimeresurus lii, in the misty mountains of Sichuan Province, China. This vibrant green snake, previously mistaken for the bamboo pitviper, was uncovered through DNA analysis conducted by scientists from the Chengdu Institute of Biology and the Giant Panda National Park. The species is named in honor of the philosopher Laozi, reflecting the region's cultural heritage and conservation efforts. The Huaxi Green Pitviper exhibits sexual dimorphism; males possess bold red and white stripes and amber eyes, while females have a simpler yellow stripe and orange-yellow eyes. Growing up to 80 centimeters (approximately 32 inches), this venomous snake inhabits the humid forests of Mt. Emei and Xiling Snow Mountain, areas recognized as global biodiversity hotspots. The discovery underscores the importance of ongoing field surveys to uncover the many unknown species that still exist in well-explored regions.
