Assessment Information [top]

Red List Category & Criteria: Vulnerable A3c ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Dávalos, L. & Mantilla, H.
Reviewer(s): Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Listed as Vulnerable because it is suspected that a population decline, estimated to be >30% would be met over the next 10 years, inferred from the rapid loss of habitat to agriculture, logging and illicit crops. This species is poorly known, restricted to forest habitats, and very susceptible to habitat conversion. This species needs taxonomic investigation and should be reviewed following an evaluation.
1996 Vulnerable
