Habitat and Ecology
It occurs in leaf-litter on the ground near streams in primary or good secondary cloud forests, and has not been recorded outside forest habitat. The female lays terrestrial eggs; when they have hatched the male carries the larvae on his back to streams where they then develop further.
It is a relatively common species.
Localized threats to this species are habitat fragmentation caused by the expansion of agriculture and cattle ranching, as well as water pollution from pesticides and the fumigation of illegal crops.
The range of this species includes Parque Nacional Natural Farallones de Cali.
