Abstract
We describe a new species of frog of the family Centrolenidae, Cochranella amelie n. sp., from the central Amazonian Andean slopes, collected at the Oglan River, Province of Pastaza, Ecuador. This new species shows a very unusual combination of characters (lavender dorsum in preservative, absence of a humeral spine in adult males, transparent parietal peritoneum, white visceral peritonea, and bulbous liver). The relationships of this new species of Glassfrog are uncertain, and its assignment to Cochranella is preliminary.References
