This species is known only from the area of the type locality, Villavicencio, in the foothills of the Orinoco region, Meta Department, Colombia, at 580m asl, where it occurs in a single botanical garden surrounded by a substantial urban area.
Habitat and Ecology
It is known from small patches of forest and from a botanical garden; it has not been found in larger tracts of forest in nearby areas. It is a terrestrial and diurnal species, and it lays its eggs in the leaf-litter. The males probably take care of the eggs and then move the larvae to small streams for development.
It is scarcely distributed in its tiny area of occupancy. There are few specimens known, and it was last seen in 2002. Searches in outlying areas have not turned up any individuals.
Habitat fragmentation and destruction caused by the expansion of human settlement, and water pollution, are the primary threats to this species.
This species is not recorded from any protected areas, and there is an urgent need for protection of its remaining habitat. Further survey work is needed to determine this species' current population status and natural history.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered because its Area of Occupancy is probably less than 10km2, its distribution is severely fragmented, and there is a continuing decline in its Extent of Occurrence, and in the extent and quality of its habitat.
