Known from Mont Vatovavy, Ambositra and Anosibe an'Ala. The distribution range is very fragmented and in each site the number of individuals is very low; the whole population is estimated to be fewer than 40 mature individuals. There are known threats to the habitat which may be causing population declines, but these have not been definitely documented. This species qualifies for a Critically Endangered listing based on the small population size.
