This species is known only from the municipality of Santa Teresa, in the state of Espírito Santo, south-eastern Brazil, at 650-675m asl. The limits of its distribution are not known, and it might occur more widely.
Habitat and Ecology
It is found in forest, including secondary forest (but not in open areas) where it lives in leaf-litter on the forest floor. Assuming that it breeds in the same way as Zachaenus parvulus, the egg clutch is deposited on the ground under leaves, and the terrestrial larvae live and develop in a hole under the leaf-litter.
It is a hard species to find, and so its population status is unknown. However, it has been found in the type locality since the initial collection.
The area where this species is found is quite well protected (as a biological reserve), but habitat loss is taking place nearby (where it might occur), due to agricultural development, creation of wood plantations, logging, human settlement and tourism.
It occurs in the Reserva Biológica Augusto Ruschi.
Red List Status
