| Systems: |
Terrestrial |
| Major Threat(s): |
The major threat is habitat loss due to expanding agriculture and human settlements, and also logging.

| Conservation Actions: |
It has not been recorded from any protected areas, and there is therefore an urgent need for the protection of the cloud forest habitat of this species. Survey work is necessary to determine its current population status.
