Until its rediscovery in a semi-urban area of Honolulu in 1994, this species was thought to have been extirpated from Oahu. Currently, it is known on Oahu from only a single population. Stream surveys throughout the main Hawaiian Islands have determined that the extent of the distribution of this species is restricted to populations on Hawaii, Lanai, Molokai, and Oahu. A biological study of the Oahu population was made (Evenhuis et al.1995) that indicated the number of individuals at the site at any one time ranged between 20 and 100. Normally a lowland species, it has been found as high as 3,000 feet on Lanai.
