A new genus of the scleraxonian family Coralliidae (Octocorallia: Gorgonacea)

摘要

A new genus of the family Coralliidae is established for seven species having longitudinally grooved axes and autozooids seated in distinctive axial pits with beaded margins.During the preparation of a projected review of the family Coralliidae it became clear that the species currently assigned to the single genus Corallium Cuvier can be grouped in two morphological categories,those having the autozooids seated in deep axial pits with margins conspicuously beaded especially near the tips of twigs, and those without axial pits beneath the autozooids, although a depression without beaded margins may be present as in C.rubrum.
