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 about 670-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
Bayer

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 185-400 μm vs. no more than 150 μm).
P. papillata
sp. nov. is the third known white-colored species of the genus
and the fifth species found in the tropical Western Pacific.
