Rhyncogonus caudatus Van Dyke

Tailed Rhyncogonus Weevil (Rhyncogonus caudatus)

This species is endemic to the island of Huahine, where it can be found on the leaves of several non-native and native plants, including nahe (Angiopteris evecta (G. Forst.) Hoffm.).

The animals are black in colour and bear some larger, white scales on the sides of the head, the body, and above all, the abdomen, where they build some kind of a short process.

The males reach a length of about 1,15 cm, the females, with 1,4 cm, are distinctly larger. [1]

Ducula galeata (Bonaparte)

Nukuhiva Imperial Pigeon (Ducula galeata)

For a very long time this bird was thought to be endemic to the Marquesan island of Nuku Hiva – this, however, turned out to be far from the truth.

In fact, in historical times this species had a much wider geographical range, including the Cook Islands, as well as the Society Islands, and of course all of the Marquesan Islands as well. The birds were extirpated from most of their former range already by the Polynesian settlers, and had their last refuge on the island of Nuku Hiva – a situation that is called artificial endemism (… in fact, there are several other bird species within Polynesia that share the same situation …).

The Nukuhiva Imperial Pigeon is a huge bird, reaching about 55 cm from the tip of its bill to the tip of its tail, it is therefore the largest surviving pigeon species in Polynesia.

Nevertheless the bird is far from being flightless.

The endangered species was reintroduced to another of the Marquesasn islands, Ua Huka, were it is breeding since, and the future of this impressive species seems to be a good and save one.

Mautodontha consobrina (Garrett)

Huahine Mautodontha Snail (Mautodontha consobrina)

This species, which comes from the island of Huahine, was described in the year 1884.

The shells reach an average size of 0,38 cm in diameter.

Andrew J. Garrett, the species’ author writes in the year 1884.:

Rare and peculiar to one valley.

This statement is all, that is known about this now extinct species, of which obviously only seven museum specimens are in existence.
