Justification
Listed as Data Deficient in view of continuing doubts as to its taxonomic validity as well as uncertainty about its extent of occurrence. Its known extent of occurrence is less than 250 km2 and the extent and quality of its habitat are probably declining; however, it is a common species that is tolerant of the current levels of habitat disturbance, and its populations appear to be stable despite being hunted for subsistence use. If human populations continue rise in this area, and the taxonomic issues are resolved, this species could quickly qualify for a threatened category.
