Reviewer(s): Johnson, C.N. & Hawkins, C.
Listed as Endangered because it is suspected to have undergone at least a 50% population reduction in the last three generations (i.e., 30 years) that has not ceased, due to hunting pressures and loss of habitat.

Conservation Actions [top]

Conservation Actions: This species occurs in several protected areas. Further studies are needed into the taxonomy, distribution, abundance, natural history, and threats to this species.
