Justification of Red List category
This species is estimated to have a very small population which is likely to be declining through habitat loss, leading to its categorisation as Endangered. If its range were judged to be severely fragmented, it may be classified as Critically Endangered; conversely if it were found to be highly tolerant of habitat perturbation it may be downlisted to Vulnerable.
