The eastern caenolestid (Caenolestes sangay ) is a shrew opossum found on the eastern slopes of the Andes in southern Ecuador.
The origin of the genus name (Caenolestes ) drives from the Greek words kainos ("new") and lestes ("robber", "pirate"). The origin of the species name (sangay ) derives from Sangay National Park, which is the largest Andean national park in Ecuador. The park itself is named after a volcano called Sangay, one of Ecuador's most active volcanoes that lies within the park. Sangay National Park was the site of the discovery of the eastern caenolestid in 2010.
