| 英文摘要 | A new species of bubblegum coral,Paragorgia rubra sp.nov.,discovered from a seamount at a water depth of 373 m near the Yap Trench is studied using morphological and molecular approaches.Paragorgia rubra sp.nov.is the fourth species of the genus found in the tropical Western Pacific.The new gorgonian is red-colored,uniplanar,and measures approximately 530 mm high and 440 mm wide,with autozooids distributed only on one side of the colony.Paragorgia rubra sp.nov.is most similar to P.kaupeka Sánchez,2005,but differs distinctly in the polyp ovals with large and compound protuberances(vs.small and simple conical protuberances) and the medullar spindles possessing simple conical protuberances(vs.compound protuberances).Moreover,P.rubra sp.nov.differs from P.kaupeka in the smaller length/width ratio of surface radiates(1.53 vs.1.75).The genetic distance of the mtMutS gene between P.rubra sp.nov.and P.kaupeka is 0.66%,while the intraspecific distances within Paragorgia Milne-Edwards & Haime,1857 except the species P.regalis complex are no more than 0.5%,further supporting the establishment of the new species.Furthermore,the ITS2 secondary structure of P.rubra sp.nov.is also different from those of congeners.Phylogenetic analyses indicate Paragorgia rubra sp.nov.and P.kaupeka form a clade,which branched early within Paragorgia and diversified approximately 15 Mya. |
