Partula faba was a species of partulid within the genus Partula. The species is commonly referred to as Captain Cook's bean snail, and was endemic to Raiatea and Tahaa.

Distribution

P. faba's historical distribution represents both Tahaa and Raiatea, but it was extirpated by Euglandina after its introduction.

Captive breeding

P. faba was being sustained in the breeding program, but a slow but constant decline set in until the last P. faba died in February 21, 2016.

Phylogeny

Phylogenetic analyses found that P. faba is closely related to P. turgida.

Taxonomy

P. faba was originally described in the genus Limax (L. faba), before being moved to Helix (H. faba) and later moved again to the newly-erected genus Partula.

Subspecies

Partula faba faba - Raiatea. This subspecies was the one initially described and the subspecies of the very first Partula to be described. This subspecies was the one maintained in captivity until 2016.

Partula faba subangulata - Tahaa. This species was larger and endemic to Tahaa. It was not collected for captivity and went extinct sometime in the 1980s to 1990s.
