“…Placostylus hongii ( Fig. 2A) has been recorded from sites between Whangaroa and Whangarei on the mainland Northland and on offshore islands between Whangaroa and Great Barrier Island (Powell 1979;Browne 1980;Brook and McArdle 1999). Placostylus ambagiosus Suter, 1906 (Fig.…”

“…Some of the New Zealand taxa are critically endangered: the Three Kings species, P. bollonsi, is confined to two small populations distinguished as separate subspecies (Powell 1948(Powell , 1951aClimo 1973) (Brook and Laurenson 1992). These populations are restricted by lack of suitable habitat and are not threatened significantly by predators.…”

Large (5-9 cm in length) land snails of the genus Placostylus are found in New Caledonia and the Loyalty Islands, northern New Zealand, the Three Kings Islands just north of New Zealand and on Lord Howe Island. Their presence on Lord Howe, an oceanic island less than 6 million years old, has been an intriguing biogeographical question. Maximum parsimony and maximum likelihood analyses using cytochrome c oxidase subunit I sequence data suggest that the Lord Howe Island and mainland New Zealand taxa are sisters, but that the Three Kings taxon is independently derived, possibly from New Caledonian stock. Placostylus colonies throughout the area of the present study are under considerable threat, with many intraspecific forms and some species threatened and some listed as endangered species. The taxonomic and conservation status of the Lord Howe Island populations are discussed.

Genetic diversity and taxonomy: a reassessment of species designation in tuatara (Sphenodon: Reptilia)

et al. 2009

The identification of species boundaries for allopatric populations is important for setting conservation priorities and can affect conservation management decisions. Tuatara (Sphenodon) are the only living members of the reptile order Sphenodontia and are restricted to islands around New Zealand that are free of introduced mammals. We present new data of microsatellite DNA diversity and substantially increased mtDNA sequence for all 26 sampled tuatara populations. We also re-evaluate existing allozyme data for those populations, and together use them to examine the taxonomic status of those populations. Although one could interpret the data to indicate different taxonomic designations, we conclude that, contrary to current taxonomy, Sphenodon is best described as a single species that contains distinctive and important geographic variants. We also examine amounts of genetic variation within populations and discuss the implications of these findings for the conservation management of this iconic taxon.
