This species is known from the Southern Amazon basin in drainage of Madeira, Tapajos and Jurua rivers, Brazil.
Habitat and Ecology
This species can be found in leaf-litter in lowland rainforest. Its reproductive mode is unknown, though it is likely to be by direct development. Its ability to adapt to secondary habitats is not known.
It appears to be stable, but population size hard to assess because it can be sampled only with pitfall traps.
Deforestation from agriculture and logging is probably impacting local populations, but overall, this species is unlikely to be threatened.
It probably occurs in several protected areas.
