Justification

This species has been extirpated from its type locality, and its presence in Viet Nam is severely threatened by logging activities. It is known from four other sites in southern and southwest China, where it has a very localised distribution. The Chinese populations currently have no known threats, and it may be more widely spread than is currently known, so pending further information it is assessed as Near Threatened (close to meeting VU under D2).

Conservation Actions
More research is needed on this species' distribution, habitat and potential threats. This species would benefit from site protection in the remaining distribution in Viet Nam.
