This species is known only from the type locality and its vicinity between Papallacta and Cuyuja in Napo Province, Ecuador, at 2,660-2,750m asl. It probably occurs elsewhere, though it is unlikely to be a widespread species.
Habitat and Ecology
It occurs in upper montane cloud forest, and presumably breeds by direct development. There is no information on its adaptability to disturbed habitats.
There is no recent information on the population status of this species.
The major threats are likely to be deforestation due to agricultural development, creation of plantations, logging, and human settlement.
It is not known to occur in any protected areas, and habitat protection is urgently needed.
