Distribution and Habitat
Country distribution from AmphibiaWeb's database: Ecuador, Peru
The species has only been found on the central Amazonian Andean slopes of Pastaza province of Ecuador, at 600m asl. The holotype and paratype were both collected in a primary forest, on leaves overhanging a stream connected to the Oglán River.
Life History, Abundance, Activity, and Special Behaviors
Both males were found perched on Heliconia leaves about 0.8 m above ground and overhanging the water. The frogs were calling from the upper surface of the leaves.
The paratype (a male) was found next to a single-layer egg clutch left on leaf upper surface.
The specific name alludes to Amelie, a character in the movie "Le Fabuleux Destin d'Amélie Poulain." The authors wished to show that as in the movie where little details play an important role in the "joy of living," amphibians and reptiles may be small but play an important role in the health of our planet.
