Habitat and Ecology
This species occurs among the forest leaf-litter in primary and secondary forest and forest edge. It presumably breeds by direct development like other species in the genus. It has not been recorded outside forest.
It is a locally common species.
Habitat loss due to deforestation, infrastructure development for human settlement, and fires are major threats to the species.
The range of the species includes a few protected areas. More research into the species' Extent of Occurrence and ecological requirements is needed.
The validity of this species needs to be assessed.
