Justification of Red List category
This species qualifies as Critically Endangered because it has a tiny population which is suspected to be in decline owing to habitat degradation. It occupies a very small area of primary forest which, although it is not severely threatened, remains unprotected and might be vulnerable in the future. It is unclear whether introduced predators are impacting its population. Recent observations extend the known range, elevation and habitat, but the known population currently remains extremely small.
