FIGURE 5 Combined 28S in The stoloniferous octocoral, Hanabira yukibana, gen. nov., sp. nov., of the southern Ryukyus has morphological and symbiont variation
FIGURE 5 Combined 28S rDNA+COI+mtMutS+ND6 phylogenetic reconstruction for 35 clavulariid specimens, including Hanabira yukibana, gen nov., sp. nov., and Clavularia spp. from Okinawa (OKA) and Irio- mote (IRI) Islands and sister taxa, Knopia octocontacanalis Alderslade & Mcfadden, 2007. Parasphaerasclera rotifera and Eleutherobia grayi were used as outgroup. The best maximum likelihood tree is shown, with values at branches representing bootstrap probabilities (>50%) and posterior probabilities from the Bayesian inference (>0.50), respectively. Polyp variation for H. yukibana is illustrated for the three groups by colour and corresponding in situ photographs.
