Recorded from the islands of Oahu, Molokai, and Lanai. It is currently known from only two small areas on the island of Oahu. Fewer than 2,000 individuals are believed to remain. Most of the taxon's habitat on Oahu has been destroyed by urban development and agriculture. Additional threats to the taxon include habitat degradation by invading alien plants, and fire.
