Although recent records suggest that this species may be widespread and overlooked rather than rare, and that it tolerates habitat disturbance, it is precautionarily treated as Vulnerable because it is thought to have a small population, which is in decline owing to forest loss and degradation. Fieldwork is required to clarify its status, and this may lead to its downlisting.
