The Polynesian sandpipers form the genus Prosobonia. They are small wading birds confined to remote Pacific islands of French Polynesia. Only one species is now extant, and it is rare and little known. This bird is sometimes separated in the genus Aechmorhynchus, restricting the genus to the extinct southern forms.

The Tuamotu sandpiper is an endangered member of the large wader family Scolopacidae, that is endemic to the Tuamotu Islands in French Polynesia. It is sometimes placed in the monotypic genus Aechmorhynchus. A native name, apparently in the Tuamotuan language, is kivi-kivi.
