Extinction

The only recorded living specimen of Dieffenbach's rail was captured in 1840 by Ernst Dieffenbach, who is commemorated in the scientific and common name of the species. It became extinct due to hunting and introduced predators, perhaps soon after 1872.

Taxonomy

The Dieffenbach's rail was sympatric with the flightless Chatham rail (Cabalus modestus). Their sympatry suggests parallel evolution after separate colonisation of the Chatham Islands by a common volant ancestor, presumably the buff-banded rail (Hypotaenidia philippensis).[3] A 2014 genetic analysis found that the taxa were not particularly closely related, with Dieffenbach's rail being sister to the group of Hypotaenidia including the buff-banded rail, while the Chatham rail was found to be in a more basal position.[4] It is still considered to be in the genus Gallirallus by some experts.
