Abstract
New Zealand land snails in the genus Sinployea Solem, 1983 are revised.
There are 17 species, of which 16 are new. The new species are illustrated
with line drawings and photographs of the shells and with drawings of the
reproductive anatomy. Shell and reproductive anatomical characters
of Sinployea, Calymna Hutton, 1883, Flammoconcha Dell, 1952, and other
charopid species suggest grouping these in subfamily Charopinae tribe
Flammulinini Crosse, 1895, rather than in Flammoconchinae Schileyko, 2001.
The congruence of the tectonic history of the southwest Pacific
with the distributional boundaries of Sinployea and other charopid and
punctid species is discussed in detail. Conservation threat rankings are
recommended

Discussion topics include: Sinployea species diversity and Central Pacific
large igneous plateaus, Sinployea species diversity and Central Pacific
large igneous plateaus, Volcanism and metapopulation survival, Allopatry
and disjunctions along subduction zones, NZ Alpine Fault.

A concluding statement: "SW Pacific charopids with predominantly spirally
sculptured embryonic shells and male genitalia with penial glandular
appendages or pocket pilasters form a regional band from the eastern
Australian continent across Zealandia into the Pacific. Within this
regional band, allopatric species are found on islands separated by
back-arc spreading, and elsewhere they have disjunct distributions along
extinct subduction zones or are transcurrently displaced along the Alpine
Fault and VMFZ and across the Havre Trough. At the same time, most
Sinployea species are found in an area defined by the Ontong Java,
Manihiki, and Hikurangi plateaus. Congruence between the
underlying geological history and the overlying species distributions at a
regional scale suggests a metapopulation survival scenario, as proposed by
Solem and others."
