Habitat and Ecology

The species inhabits the Evergreen Lowland Forests in northwestern Ecuador. It is active during the night and has been found on leaves along streams. Males call from the upper sides of leaves, and females deposit pigmented eggs on the upper sides of leaves (Guayasamin and Trueb, 2007). The species requires permanent streams for breeding (J.M. Guayasamin, pers. comm. 2008).


The species is locally abundant at the localities where it has been found (J.M. Guayasamin, pers. comm. 2008).
