Justification of Red List category
This species has a very small range, within which it is known from only 4 forest patches. It is therefore currently classified as Vulnerable, but evidence of a continuing decline in its population or range would result in its uplisting to Endangered. Conversely, it may prove to be more widely distributed and to occupy a continuous distribution between the known locations, in which case it may be appropriate to downlist to a lower threat category.
