Justification of Red List category
This species has been listed as Critically Endangered (Possibly Extinct) because, of three known individuals in 1998, one died in captivity in 2004 and the remaining two individuals have not been seen since 2003 and 2004. It may be extinct, but continuing surveys in all areas of potential habitat are needed to confirm that no other individuals survive. If any do still survive, the total population must be tiny.
1-49 mature individuals
