摘　　要：A new species of bubblegum coral,Paragorgia papillata sp.nov.,discovered from a seamount located on the Caroline Ridge at the water depth of 858 m,is studied using morphological and molecular approaches.The new gorgonian is white-colored,uniplanar with prominent autozooids,and measures about670-mm high and 690-mm wide.The genetic distance and phylogenetic analysis showed that P.papillata sp.nov.was closely related to P.coralloides Bayer,1993,but the former differs morphologically from the latter by its prominent calyces(diameter 2.0-4.0 mm and height 1.5-3.0 mm vs.both diameter and height about 1 mm),white cortex(vs.pink),regular 8-radiates in surface cortex(vs.mostly 8-radiate derived globular radiates)and highly ornate medullar spindles(length 185-400μm vs.no more than 150μm).P.papillata sp.nov.is the third known white-colored species of the genus,and the fifth species found in the tropical Western Pacific.
