This species occurs in the Pacific lowlands of northwestern Colombia in the drainages of the Atrato and San Juan rivers, from 70–300 m asl.
Habitat and Ecology
It is a subterranean species living in lowland tropical forests and secondary growth forest, but it has not yet been found outside forests. It is not known whether or not it can survive in degraded, open areas. Although there is limited ecological information, it is expected to be oviparous with direct development, as with other congeners (San Mauro et al. 2014).
It appears to be a common species, and its population trend is unknown.
Deforestation as a result of expanding agriculture is a potential threat, but there is not enough information to confirm this.
This species occurs in the Utria National Natural Park, Reserva Forestal Protectora Nacional Rio Anchicayá and Reserva Forestal Protectora Regional De Bitaco. A number of conservation projects are operating in the Colombian Choco, which could benefit this species.
More information is needed on this species' distribution, population status, natural history, and threats. Further research is also needed to resolve the taxonomy of this species.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its relatively wide distribution and presumed large population.
This is a poorly circumscribed species in need of taxonomic review (M. Wilkinson pers. comm.).
