This species is known only from the type locality, Quebrada Guanguí, in the upper Río Saija drainage, in the department of Cauca, Colombia, from 100-200m asl. It is most likely a wider ranging species, but more sampling is needed to confirm this.
Habitat and Ecology
It calls from beneath leaf-litter and from holes in the ground covered with leaf-litter in humid tropical forest. The eggs and larvae develop in small temporary rain pools.
It is thought to be a rare species, but it is a secretive forest species so this has not been confirmed.
There are no threats to the habitat at the type locality at present because there is not much human influence in the area.
The type locality is not within a protected area. Conservation of the species' habitat is advisable as it is unlikely to tolerate significant disturbance of its habitat. More research into the species' Extent of Occurrence, ecological requirements and population status is needed, in particular to determine if it occurs outside the vicinity of the type locality.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of continuing uncertainties as to its extent of occurrence, status and ecological requirements.
