Alcyoniina
The suborder Alcyoniina is a former octocoralian taxon belonging to the broadly conceived order Alcyonacea.
Since a 2022 revision, almost all the families of former Alcyoniina belong to the order Malacalcyonacea, within which, however, they do not form a monophyletic taxon. Only the problematic Alcyoniinan family Parasphaerascleridae now belongs to the order Scleralcyonacea.
Members of Alcyoniina are found mainly in the Pacific and Indian oceans.
