Partula affinis is a species of partulid within the genus Partula. The species is rarely referred to as the similar partula,[3] and is endemic to Tahiti.

Distribution

[edit]

This species' historical distribution represents almost all of Tahiti, but now its modern distribution includes only one population in Tahiti Iti, making it now considered a single valley endemic.[1]

Captive breeding

[edit]

Partula affinis is in the international Partula breeding program and the conservation efforts for this species have been very successful, allowing reintroductions since 2015.[4]

Phylogeny

[edit]

Phylogenetic analyses confirmed that P. affinis is the sister species of P. otaheitana.[5]

Taxonomy

[edit]

P. affinis was originally described as a subspecies of P. otaheitana (P. otaheitana affinis) but is now recognized as a distinct species.
