Assessor/s:

Bidau, C. & Lessa, E.

Reviewer/s:

Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)

Justification:
Listed as Near Threatened because its extent of occurrence is probably not much greater than 20,000 km², and it occurs in several small, widely separated subpopulations, thus making the species close to qualifying for Vulnerable based on range size and decline (criteria B1b(iii)).

History:

1996

–

Lower Risk/least concern (Baillie and Groombridge 1996)
