Maitua Orangia Snail (Orangia maituatensis)
This species was described in 1976, it is endemic to the island of Rapa, Austral Islands, where it appears to be (or have been) restricted to cliffs near Maitua in the southern part of the island, and Mt. Tautautu.
The shells reach sizes of about 0,38 to 0,44 cm in diameter. [1]
***
The Maitua Orangia Snail was not found during recent field surveys and may be extinct. [2]

Orangia cookei ssp. cookei Solem
Cooke’s Orangia Snail (Orangia cookei ssp. cookei)
The genus Orangia contains three species, of which one again, is split into three subspecies; all are endemic to the island of Rapa, Austral Islands; and all were described together in 1976. [1]
***
Cooke’s Orangia Snail is thought to consists of three subspecies, besides the nominate race these are, the Montane Orangia Snail (Orangia cookei ssp. montana Solem), and the Mt. Tautautu Orangia Snail (Orangia cookei ssp. tautautuensis Solem).
The nominate race is (or rather was) restricted to the vicinity of Mt. Orangi, Mt. Tanga, and Mt. Tepiahu.
The shells reach sizes of about 0,33 to 0,45 cm in diameter. [1]
***
The Montane Orangia Snail appears to be the sole survivor of its genus, it is the only species that was found during recent field work. [2]

Orangia sporadica Solem
Sporadic Orangia Snail (Orangia sporadica)
The Sporadic Orangia Snail was described in 1976.
The species is known from 102 specimens which all were collected in 1934. The snails were found hiding under stones in limited quantities at scattered localities.
The shells reach sizes of about 0,36 to 0,43 cm in diameter.
***
The Sporadic Orangia Snail was not found during the most recent field studies and may thus be extinct. [2]
