Opus has a page for Tristan Moorhen Gallinula nesiotis, tagged as extinct at the genus category, but the page lists a surviving subspecies G. g. comeri. This is split by IOC as Gough Moorhen G. comeri, but I don't know what Clements and H&M do with it. If still kept as lumped, then the extinct tagging of G. nesiotis needs to be removed; if split, a new page for G. comeri is needed.
