Researchers from the Museo de Zoología at Catholic University of Ecuador explored a little-investigated region of the Ecuadorian Andes and found two new frogs in the highly diverse genus Pristimantis.

Meanwhile, South American and North American scientists teamed up on the discovery of another frog in that genus – Pristimantis pluvialis.

The pair of species from Ecuador, P. llanganati and P. yanezi, were found in the Llanganates National Park, which has vast swaths of land that can only be accessed on foot. For that reason, it holds great promise for new animal discoveries.

Like other frog species inhabiting the park's forests, P. llanganati and P. yanezi have a "spiky" look and develop directly into frogs, without any tadpole stage and metamorphosis.

The researchers say that with so few frogs cataloged in the region, it's likely there are yet more Pristimantis species to be found.
