Scientific Name: Phalanger vestitus (Milne-Edwards, 1877)
Common Name(s):
English Stein's Cuscus
French Couscous Noir
Taxonomic Notes: The four widely separated subpopulations of Phalanger vestitus are distinctive and its taxonomy needs to be re-evaluated (K. Helgen pers. comm.).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2015-06-15
Assessor(s): Leary, T., Singadan, R., Menzies, J., Helgen, K., Wright, D., Allison, A., Aplin, K., Salas, L. & Dickman, C.
Reviewer(s): Johnson, C.N. & Hawkins, C.
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. The four subpopulations of this species, however, may represent four different species (see Taxonomic Notes). Some of these subpopulations if elevated to species would probably warrant a threatened status.
