An expedition into the cloud forests of the Bolivian Andes has uncovered 20 species new to science, including a frog that may be the smallest in the Andes, a new venomous pit viper, four butterflies, and four orchid species.
Along with the newly described species, the research team also “rediscovered” four species believed to be extinct, including the devil-eyed frog (Oreobates zongoensis), not observed on record for 20 years, and a satyr butterfly (Euptychoides fida), not recorded for 98 years.
