Population [top]

Population: It is apparently a common species.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: It lives in leaf-litter on the floor of lowland tropical rainforests, and has not been found in modified habitats.
Systems: Terrestrial

Threats [top]

Major Threat(s): This species lives in a remote area that is at least partially protected, so it is unlikely to be seriously threatened by any particular pressures. However, deforestation and habitat degradation due to smallholder agriculture and logging probably threaten local populations, and gold extraction might pose a future problem, if illegal mining starts in the area where it occurs.

Conservation Actions [top]

Conservation Actions: The range of some populations falls within established national parks and a Biosphere Reserve (Parque Nacional Serranía de la Neblina and the Reserva de Biosfera Alto Orinoco-Casiquiare).
