Justification of Red List category
This species has not been recorded with certainty on Kaua'i since 1989 nor on Hawai'i since 1987, and recent searches specifically for it have failed. It may have been driven extinct by habitat loss, introduced rats, and in particular from malaria from introduced mosquitoes. However, it cannot yet be presumed to be Extinct until all potential areas have been surveyed, particularly in Ka`u, Waiakea, and Pu`u Maka`ala, and recent unconfirmed reports have been followed up by systematic searches. Any remaining population is likely to be tiny, and for these reasons it is treated as Critically Endangered (Possibly Extinct).
