This species is classed as Near Threatened as it has been suspected to have a moderately small range, in which it is threatened by agricultural encroachment and logging. Recent mapping of the species's range suggests that its Extent of Occurrence may be larger than previously thought, and may not approach the thresholds for Vulnerable based on its range size; if it is not found to approach any other thresholds for classification as Vulnerable it may warrant downlisting to Least Concern.
