Justification of Red List category
The last confirmed sighting of this species was in 1989, with only several recent unconfirmed sightings despite extensive effort in a large proportion of the historic range. However, it cannot yet be presumed to be Extinct until further surveys have confirmed that there is no reasonable doubt that the last individual has died. Any remaining population is likely to be tiny, and for these reasons it is treated as Critically Endangered (Possibly Extinct).



Population size: 1-49 mature individuals
