Justification:

The extent of occurrence of this species covers less than 14,380 km². This geographic range is severely fragmented and undergoing continuing decline in area, extent and quality of habitat. The number of mature individuals is also known to be in decline. Based on these premises, the species is listed as Vulnerable.

Previously published Red List assessments:

Geographic Range [top]

Range Description:This species occurs in south east coastal Madagascar. Currently known only from the area of its type locality, the Manombo Special Reserve and Agnalahaza Forest. Further studies are required to determine its exact distribution, and especially the limits with regard to neighbouring species (A. peyrierasi and A. meridionalis). The extent of occurrence (EOO) is estimated to be less than 15,000 km2.
