Way of life

Little is known about his way of life. This species is independent of water bodies, as it does not go through an aquatic tadpole stage, but a direct development of the eggs takes place.


The IUCN classifies this species in the critically endangered category . The last evidence comes from the 1980s and despite intensive searches in 2003 and 2004, this salamander could not be rediscovered. The habitat in the type locality has been severely damaged and severely degraded by clearing, agricultural use (especially potato cultivation) and the expansion of human settlements.
