Morphology and phylogenetic analysis of five deep-sea golden gorgonians (Cnidaria, Octocorallia, Chrysogorgiidae) in the Western Pacific Ocean, with the description of a new species.

ABSTRACT: Explorations of seamounts in the Western Pacific Ocean and South China Sea resulted in collecting 18 specimens of golden gorgonians. Based on the morphology and the genetic analysis of mtMutS, they are described as one new species, Chrysogorgia carolinensis sp. nov., and four known species, including Chrysogorgia dendritica Xu, Zhan & Xu, 2020, Metallogorgia melanotrichos (Wright & Studer, 1889), Metallogorgia macrospina Kükenthal, 1919, and Pseudochrysogorgia bellona Pante & France, 2010. Chrysogorgia carolinensis belongs to the Chrysogorgia "group A, Spiculosae" with rods or spindles distributed in the polyp-body wall and tentacles, and differs from all of its congeners except C. dendritica by the 1/3L branching sequence and
