Hyloxalus sylvaticus

It is endemic to northern Peru and found on the Amazonian slopes of the Eastern Andes and in the Huancabamba Depression.

The throat, posterior of the belly, and ventral surfaces of the hind legs are dark yellow or orange in color.

[3] This frog lives in cloud forests on the east side of the Andes Mountains and in the Huancabamba Depression.

It is threatened largely by deforestation in favor of agriculture and by the fungal disease chytridiomycosis.

[1] Because this frog lives in mountaintop habitats, scientists speculate that climate change could pose further threat, either by rendering its habitat too dry or through competition from other species from lower elevations migrating uphill [1]
