This species is known from several localities in Colombia (Florencia, in Caquetá Department, on the eastern slope of the Cordillera Oriental, and Iconouz, in Tolima Department, on the western slope of the Cordillera Oriental), and from the Amazonian slopes of the Ecuadorian Andes (Napo province). Its altitudinal range is 1,100-1,800m asl.
Habitat and Ecology
It occurs on streamsides in montane cloud forests, including in secondary forest, providing there is good vegetation cover close to streams. It breeds at streams, with the eggs laid on leaves overhanging the water.
It is common where it has been found in Colombia. In Ecuador, it is only known from one specimen (Guayasamin et al., 2006).
There is very little information on threats to this species, but they are likely to include: deforestation due to agricultural development, cultivation of illegal crops, fire, logging, and human settlement; introduction of alien predatory fish species in streams; and pollution resulting from the spraying of illegal crops. Chytridiomycosis also cannot be ruled out as a potential threat.
This species is not known from any protected areas. Surveys are urgently needed to determine the true population status of this species and, if necessary, an ex situ population should be established.
