Four localities (Tasmania, Macquarie Ridge, New Zealand and Antarctica) of the primnoid bottlebrush octocorals from the South Pacific and Southern Ocean were assessed. The top section evaluates a grouping in which all collecting localities are part of one unique population (i.e., ACC as no barrier), while the bottom section evaluates a scenario in which the sub-Antarctic localities are grouped as one population (Tasmania, Macquarie Ridge, and New Zealand) compared to Antarctica (i.e., ACC as a barrier)
