In the 1992 recovery plan for the O`ahu tree snails of the genus Achatinella, Achatinella cestus was classified as having the status of possibly being extant. A. cestus was historically located on the leeward slopes of the southern Ko`olau Mountains. The most recent sighting of A. cestus was in 1966 on Hawai`i Loa Ridge. Surveys were conducted in various areas of the historical range of A. cestus from 2002 to 2009, but it was not sighted during any of those surveys.
