This species occurs on the eastern slopes of the Andes, from Napo Province in Ecuador, north to Florencia, Caqueta Department, in Colombia. Specimens assigned to this species have also been reported from the eastern slopes of the Central Cordillera, in Antioquia, Caldas and Tolima Departments, Colombia. Its altitudinal range is about 1,000-2,000m.
Habitat and Ecology
It is always associated with streams in montane forest. It does not occur in degraded forest. The eggs are placed under rocks near streams, and the tadpoles develop in streams.
It is a common species.
The major threats are: deforestation for agricultural development, illegal crops, logging, and human settlement; introduction of alien predatory fish in streams; and pollution resulting from the spraying of illegal crops. Also, chytridiomycosis is a possible future threat.
Its distribution overlaps with Parque Nacional Sumaco Napo-Galeras and Reserva Ecológica Cayambe-Coca in Ecuador. It is not known from any protected areas in Colombia.
Red List Status
Least Concern (LC)
The populations reported from the eastern slopes of the Cordillera Central in Colombia are probably not conspecific with Hyloxalus bocagei (T. Grant pers. comm.). Santos (2002; unpublished Licenciatura thesis, Pontificia Universidad Católica del Ecuador) provides molecular evidence that this nominal taxon is composed of at least seven species in Ecuador. Further research will probably show that H. bocagei is restricted to populations at and near the type locality.
