Taxonomic Remarks
Three subgenera of the Hamacantha genus are recognized to date: Hamacantha, Vomerula and Zigherpe. The first has oxas as main spicules, the second styles and the third tylostyles. This new species is classified for this reason within the sub genus Hamacantha. The genus is characterized by the possession of special spicules called diancistras so it is easily identifiable and relatively common in the Deep-Sea and in dark environments around the world.
