The species is found on the islands of Pohnpei and Kosrae where its extent of occurrence is approximately 485 km². The species' area of occupancy is far less due to the distribution of available habitat (rivers). The species has been recorded from three locations (three rivers). There is continuing decline in the area of occupancy (the species was previously recorded from three rivers and more recently from only two), the area and quality of habitat, and in the number of locations (now two). This species is threatened by agricultural run-off from sakau production, which is altering the quality of rivers (i.e. the species' habitat).
The species is listed as Endangered.
