Range DescriptionThis species is endemic to the Federated States of Micronesia, where it is known from Pohnpei and Kosrae Islands in the Eastern Caroline Islands (Parenti and Maciolek 1993). It was described from 17 specimens from one river on Pohnpei. The island of Pohnpei is a total of 355 km in area. Kosrae island is 110 km in area.
There is a continuing decline in the area of occupancy (previously the species was recorded from three rivers and more recently from only two (Buden et al. 2001)), in the area and quality of habitat, and in the number of locations in which the species is found (now two).
