On a global scale, the complex encompassed six lineages, two of which were pantropical and the remainder seemingly were restricted to the Judo-Pacific basin. Caulerpa racemosa var. cylindracea, a fast-spreading introduced taxon in the Mediterranean Sea and the Canary Islands, was previously thought to be restricted to southwestern Australia; it was newly reported here for New Caledonia and several northern Australian locations, including the Great Barrier Reef. 034 UR227 Malaisie
