This species is widely distributed in the eastern lowlands and cordilleras of central Panama, and from west of the Andes from the Panamanian border to northern Cauca department, in Colombia. It occurs at elevations up to 1,040 m asl.
Habitat and Ecology
It is a large terrestrial species of humid lowland and montane forest, which requires moist conditions and hence is restricted to primary forest. It reproduces by direct development, but the egg deposition site is not known.
It is generally considered to be a rare species throughout its range. Due to ongoing local declines in the extent and quality of habitat, the population is suspected to be decreasing.
General habitat loss due to the destruction of natural forests from logging are localized threats, but there are no major threats to the species' overall survival at present.
The species has been recorded from three protected areas in Panama, and from several protected areas in Colombia.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution and presumed large population.
This species was previously within the genus Eleutherodactylus (Crawford and Smith, 2005). The name "biporcatus" also has been used for Eleutherodactylus opimus, a newly described species, which occurs from central Panama to western Colombia (Savage and Myers 2002).
