Partula affinis

Partula affinis is a particularly confusing species. It was thought to be a subspecies of P. otaheitana but coexisted with it over much of Tahiti. In some areas the two species were clearly distinct, but in others P. affinis was remarkably variable in shape. In the south of Tahiti is seems that the P. otaheitana populations may actually have been P. affinis. One of the questions still to be addressed is: were theses two forms in the process of speciation, or where they two sister species that hybridised in the south? Today P. affinis is Critically Endangered in the wild but is successful in captivity.
