Distributed throughout many rivers of the eastern slopes of Madagascar. The estimated extent of occurrence is less than 20,000 km² and the population is fragmented. There is a continued decline in extent of occurrence, area of occupancy and the number of mature individuals due to habitat loss from deforestation in the water catchments, and overfishing. This species is assessed as Vulnerable.
