The family Partulidae Pilsbry, 1900 is deployed throughout the high
islands of south and western Oceania as well as New Guinea. Its
metropolis is in French Polynesia, particularly the Society Islands.
Here the nominotypical subgenus of Partula Férussac, 1819, with
over 50 species, is centered. Most P. (Partula) species are
limited to a single island even though several inter-island distances
are rather small. Although predominantly arboreal, there are several
terrestrial species. Of the four genera (eleven subgenera) in the
family, those of this subgenus distinguish themselves with a variety of
color patterns, more conspicuous in the tree-dwelling species. Most
islands have more than a single species, and ecological as well as
geographical forces seem to have driven their evolution. The steep
terrain isolates the many deep valleys, in which the snails prosper.
Besides allowing divergence of species, such topographic barriers have
allowed infraspecific variation (forms and subspecies) to evolve in taxa
distributed over relatively wide areas with varying landscape. Examples
of this include P. (P.) otaheitana (Bruguière,
below] on Tahiti and P. (P.) rosea [figs. 31-32] on Huahine.
Partulidae, principally the Society Islands.
Two genera, thirty-one ( 31) species, plus forms and subspecies arranged
alphabetically: locality by island.*
