What happened
Researchers have described a new species of mouse opossum, Marmosa chachapoya, discovered in 2018 in the cloud forests of the Peruvian Andes at an altitude of 2,664 meters. The species, named after the ancient Chachapoya people, is characterized by its small size and distinctive dark markings around its eyes. The only known specimen was found in Abiseo River National Park, a UNESCO World Heritage site known for its biodiversity. Genetic analysis revealed that M. chachapoya is nearly 8% genetically distinct from its closest relative, indicating it is a separate species. The discovery underscores the rich biodiversity of the Andes and suggests that many more species remain to be identified in this challenging terrain.
