Coralline algae (Corallinophycideae) are calcifying red that foundation species in euphotic marine habitats globally. In recent years, corallines have received increasing attention due to their vulnerability global climate change, particular ocean acidification and warming, because of the range ecological functions coralline provide, including provisioning habitat, influencing settlement invertebrate other algal species, stabilising reef structures. Many roles perform, as well responses stressors, been demonstrated be species-specific. order understand algae, it is essential able reliably distinguish individual which frequently morphologically cryptic. The aim this study was document diversity distribution New Zealand region using DNA based phylogenetic methods, examine a broader context, discussing implications direction for future research. Using three independent delimitation total 122 were identified across with high found both regionally also when sampling at small local spatial scales. While molecular methods mirrors discoveries, what distinguishes results reported here large number taxa (115) do not resolve type material from any genus and/or species. ability consistently accurately application authoritative names, ensure reproducible science all areas research into ecologically important yet vulnerable taxa.
