This species is known only from two localities in Ecuador: from 800-1,100m asl between Archidona and Tena in Napo Province; and from Shell, in Pastaza Province. It is likely to occur more widely.
Habitat and Ecology
It is a subterranean species in submontane forests.
There is no information on the population status of this species.
Deforestation as a result of expanding agriculture is a potential threat to this species, but there is not enough information available to confirm this.
It is in need of taxonomic review (Wilkinson pers. comm.)
The taxonomic status of this species is unclear. The Colombian specimens identified as Caecilia dunni were revalidated and assigned to C. leucocephala and C. perdita.
