This species has been recorded at few locations, of which at least one has been completely deforested since 1987. Continuing habitat loss elsewhere within this small range qualifies the species as Vulnerable. Recent information suggests the species may have a smaller range than was thought, and if this range is confirmed to be severely fragmented and continuously declining, the species may warrant uplisting to Endangered.
