Justification of Red List category
This species has not been recorded since 1860, and it may have been driven to extinction by introduced mongooses and rats, whose effect may have been exacerbated by habitat destruction. However, it cannot yet be presumed to be Extinct because there have been recent unconfirmed reports, and surveys may possibly have overlooked this nocturnal species. Any remaining population is likely to be tiny, and for these reasons it is treated as Critically Endangered (Possibly Extinct).
