This species is listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category. Despite forest fragmentation, there are still areas of significant forest cover and point localities are widespread. This species is a poorly know, since it has only been described from a few of localities, and there is still very little information on its extent of occurrence, status, threats and ecological requirements.
