This species is a nearly threatened dweller of the Chocoan rainforest of northwestern Ecuador and southwestern Colombia. Its closest relatives are distributed in Central America, whose most-recent common ancestor dispersed over the sea from the Chocó during the formation on the Isthmus of Panamá approximately 2-3 million years ago. Dendrobates sylvaticus is commonly known as the "rana diablito" or the "little devil frog" because of its reddish-orange bright color, its loud strident call, and its significant skin alkaloid load (see Santos et al., e1000056).
