This species occurs north of Villavicencio, in the eastern foothills of the Andes, Meta Department, Colombia, at 450-800m asl.
Habitat and Ecology
It is a terrestrial, diurnal species that occurs in foothill forest and lays its eggs in leaf-litter. The males probably take care of the eggs, and then move the larvae to small streams for their continued development.
It is rare, and was last seen in 2001, despite recent survey work in its range.
Habitat loss caused by agricultural expansion is the main threat to this species, and oil extraction may pose a future threat. It is also threatened by the introduced bullfrog, Lithobates catesbeianus.
Although it occurs in several small private reserves, ex situ populations should be established because the entire range of this species is nearly entirely deforested and introduced bullfrogs could eliminate the species from remaining forest fragments. Further research and survey work is required to better understand its current population status and in order to advance appropriate conservation measures for this species.
Red List Status
Listed as Endangered, because its Extent of Occurrence is less than 5,000 km2 and its Area of Occupancy is less than 500 km2, its distribution is severely fragmented, and there is continuing decline in its Extent of Occurrence, in its Area of Occupancy, in the extent and quality of its habitat, in the number of locations, and in the number of mature individuals.
This species was removed from the synonymy of Allobates brunneus by Silverstone (1971).
