Justification of Red List category
There have been no confirmed records of this species since 1964 despite some large-scale publicity campaigns. However, it may well remain extant because there have been a number of unconfirmed records in north-east China, where relatively little fieldwork has been carried out. Searches are also required in eastern Russia, and North Korea. Any remaining population is likely to be tiny, and for these reasons it is treated as Critically Endangered.
