Justification of Red List category
Endemic to Kaua'i, H. hanapepe became confined to the Alaka'i Swamp and, according to USFWS (2023) and Pratt and Pyle (2000), the last confirmed record was two specimens taken by Munro in 1899. Since its ‘rediscovery’ in 1960 (Richardson and Bowles 1964) there were at least 30 reports, the most recent of which was in 2007 (Pratt 2010). There have been no records since, despite extensive searches. Following methods developed in a series of papers published in 2017 (Akcakaya et al. 2017, Keith et al. 2017, Thompson et al. 2017), the probability that the species is extinct based on records and surveys is 0.92, and the probability it is extinct based on threats is 0.97. Accordingly, it is classified as Extinct.
