The eastern caenolestid (Caenolestes sangay) is a shrew opossum found on the eastern slopes of the Andes in southern Ecuador.[2]

Etymology

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.
