Morphology and phylogenetic analysis of two new deep-sea species of Chrysogorgia (Cnidaria, Octocorallia, Chrysogorgiidae) from Kocebu Guyot (Magellan seamounts) in the Pacific Ocean.

ABSTRACT: Two new species of Chrysogorgia Duchassaing & Michelotti, 1864 collected from Kocebu Guyot in the Magellan seamounts of the Pacific Ocean are described and illustrated: Chrysogorgia ramificans sp. nov. collected from a depth of 1831 m and Chrysogorgia binata sp. nov. collected from a depth of 1669 m. Chrysogorgia ramificans sp. nov. belongs to the Chrysogorgia "group A, Spiculosae" with rods distributed in body wall and tentacles, and C. binata sp. nov. belongs to the "group C, Squamosae typicae" with rods and/or spindles not present but only scales. Chrysogorgia ramificans sp. nov. differs from congeners by its main stem with 2/5R branching sequence at the bottom forming two large bottlebrush-shaped branch
