Unrooted ML phylogenetic tree based on mitochondrial COI-IGR with RaxML. Blue dots refer to groups on the right with more than 90% bootstrap support (over 1 000 bootstraps). Blue branches indicate Alcyonium species and red branches indicate Complexum species. *Alcyonium valdiviae has been transferred to the genus Parasphaerasclera by McFadden and Ofwegen (2013b). **Because of pre-occupation Alcyonium roseum has been renamed A. varum by McFadden and Ofwegen (2013b).
