Habitat and Ecology
This is a subterranean species in montane forest.
It is known only from the type specimen.
Deforestation as a result of smallholder farming is a potential threat to it, but there is not enough information to confirm this.
It occurs in Parque Nacional Sangay. Further research is required to resolve its taxonomic status (Wilkinson pers. comm.).
The taxonomic status of this species is unclear.
