Justification of Red List category
Strong claims for this species's persistence in Arkansas and Florida (USA) have emerged since 2004 although the evidence remains highly controversial. It may also survive in south-eastern Cuba, but there have been no confirmed records since 1987 despite many searches. If extant, the global population is likely to be tiny, and for these reasons it is treated as Critically Endangered.
1-49 mature individuals
