In Raivavae, three genera (one archipelago endemic, Australdonta) and eight species (all endemic) were previously known (Solem 1976). In particular, northeastern side of the island (east of Anatonu village) was very rich, with six syntopic species (Solem 1976), possibly due to the presence of a restricted limestone outcrop. However, the area was completely degraded by the encroachment of the village, and no live Endodontidae was found.
Another species of Minidonta, new to science, was found near Anatonu, but it is also probably extinct, as we only found old shells.
