Aubert de la Rüe’ Pseudolibera Snail (Pseudolibera aubertdelaruei)

Aubert de la Rüe’ Pseudolibera Snail was described in 2014, it is known from only three specimens which were collected in 1955 by E. Aubert de la Rüe on the island of makatea in the Tuamotu Archipelago.

The shells reach sizes of less than 0,6 cm in diameter, they are white, depressed and decorated with flammulations, the apex is flat, the spire elevated, the peripheral keel is very short. [1]

Pseudolibera cookei Sartori, Gargominy & Fontaine

Cooke’s Pseudolibera Snail (Pseudolibera cookei)

Cooke’s Pseudolibera Snail was described in 2014, it is known from nine specimens that were collected from a limestone cave at the western coast of the island of Makatea in the Tuamotu Archipelago.

The shells reach sizes of less than 0,7 cm, they are depressed, dome-shaped, white with a amber tint covering most of their surface but being absent from the vicinity of the umbilicus, their apex and spires are elevated, the peripheral keel is slightly angled towards the shell base. [1]

Pseudolibera parva Sartori, Gargominy & Fontaine

Small Pseudolibera Snail (Pseudolibera parva)

The Small Pseudolibera Snail was described in 2014, it is known from 44 specimens that were collected from the base of a limestone cliff on the island of Makatea in the Tuamotu Archipelago.

This is the smallest of the species within its genus, the shells reach sizes of less than 0,5 cm, they are depressed, white and are decorated with regularely spaced amber- to maroon-colored flammulations that quickly fade out on the shell base, the first two to three whorls, in addition to the flammulations, often show a fawn background coloration.

Pseudolibera eliporoii Sartori, Gargominy & Fontaine

Elie Poroi’s Pseudolibera Snail  (Pseudolibera eliporoii)

Elie Poroi’s Pseudolibera Snail was described in 2014, it was endemic to the island of Makatea, Tuamotu Archipelago in French Polynesia; it is known from at least 93 specimens, most of which were collected from the deposits inside the Moumu cave.

The shells reach a size of less than 0,7 cm, they are subdepressed, dome-shaped, white and bear regularely spaced amber-colored flammulations which are often more conspicuous on the shell base than apically. [1]

Pseudolibera extincta Sartori, Gargominy & Fontaine

Extinct Pseudolibera Snail (Pseudolibera extincta)

This species was described in 2014, it is known from at least 30 specimens that were collected from below rocks on the island of Makatea in the Tuamotu Archipelago.

The shells are less than 0,7 cm in diameter, they are depressed, dome-shaped, white and are decorated with regularely spaced amber-colored flammulations on the apical surface but absent from the shell base. [1]

Pseudolibera lillianae Cooke & Solem

Liliana’s Pseudolibera Snail (Pseudolibera lillianae)

Liliana’s Pseudolibera Snail was described in 1976 based on only two specimens, the considerably worn holotype and another, very small juvenile specimen, apparently both collected in 1958 on the island of Makatea in the Tuamotu Archipelago. [1][2]

***

The species is now, however, known from at least 1140 specimens, most of which were collected during intensive field studies on the island of Makatea in 2005. 

The shells are less than 0,9 cm in diameter, they are depressed dome-shaped, white with regularey spaced amber-colored flammulations, frequently interrupted at the shell periphery and vicinity of the umbilicus. [2]
