Team Lead: Santiago Ron
Expedition: Ecuador

FOUND
Rio Pescado stubfoot toad
Atelopus balios
Last seen 1995. Rediscovered after 15 years in Ecuador by Eduardo Toral-Contreras and Elicio Tapia. Researchers feared that the deadly amphibian Chytrid fungus had wiped out this species along with many other closely related species in Ecuador. This find is significant and very encouraging, offering an opportunity to protect this attractive and rare species.

POTENTIAL NEW SPECIES FOUND

BLOG POST: Lost Frogs Update: Three New Species Discovered in Colombia
New species of rocket frog – genus Silverstoneia. Living in and around streams, the rocket frogs carefully carry newly hatched tadpoles on their backs to deposit them in water to complete their development.
New species of beaked toad – genus Rhinella. Found in the rainforests of Chocó department of Colombia. In addition to its strange appearance, the beaked toad is rather unusual in that it probably skips the tadpole stage, laying eggs on the forest floor that hatch directly into toadlets.
New toad species – genus undetermined. This highly unusual species has scientists baffled: they know nothing about this species other than where it lives, which is around 2,000m elevation in the Chocó montane rainforest.
