This recently described species is currently known only from the type locality and the vicinity of the fountainhead of the Rio Jucu, next to Parque Estadual de Pedra Azul, in the municipality of Domingos Martins, in the state of Espírito Santo, Brazil. It has been observed at 1,200-1,500m asl. This species might occur a little more widely, but it might also be restricted to a single river drainage.
Habitat and Ecology
This species is associated with clean, cold upland streams with some lentic water pools in the Atlantic rainforest, and it is assumed that it does not tolerate habitat modification. Larvae have been observed in the pools.
It is presumed to have a low population density, as with other members of this genus.
The threats to this species are not known, though it is likely to be adversely affected by forest loss due to smallholder agriculture, logging, and human settlement.
Larvae of this species have been observed in Parque Estadual da Pedra Azul.
