Zurucuchu robber frog

Pristimantis w-nigrum

''Pristimantis w-nigrum'', also known as the Zurucuchu robber frog or w rainfrog is a species of frog in the family Craugastoridae. It is found on both Pacific and Amazonian slopes of the Andes in Colombia, Ecuador, and northern Peru. The species is divided to at least eight clades that are genetically highly divergent but morphologically similar; it may be a species complex.
W Rainfrog or Zurucuchu robber frog, Bellavista, Ecuador The first night tour in our Ecuador trip. Rain frogs, genus Pristimantis, can be very hard to identify for a casual like me. Luckily, Bellavista has a handy plate in the restaurant area that illustrates commonly seen frogs. That made it easy to single out this species, which is distinguished by its black/yellow outlines found all over its body. Despite these markings, it's still quite variable and likely a species complex.

Although it has a darker back, I believe this to be the same species as seen earlier in the same night tour:
