Genus Antipathozoanthus Sinniger, Reimer & Pawlowski, 2010

Diagnosis

(revised from Sinniger et al. 2010; Swain and Swain 2014, 2015; Kise et al. 2017; additions in bold). Macrocnemic zoantharians with cteniform endodermal muscle or endo-meso transitional sphincter muscle. Encrustations of the column to the outer mesoglea. No mesogleal canals or encircling sinus. Tentacles at least 26 in number. Substrate consists of antipatharians, external surfaces of parchment-like tubes of polychaetes, or calcium carbonate (coral reef).

Type species.

Gerardia macaronesicus Ocaña & Brito, 2003, by original designation.

Remarks.

We herein modify the diagnosis of Antipathozoanthus , as A. tubus sp. nov. is clearly located within the clade of Antipathozoanthus with very high support in our molecular phylogenetic analyses. Skeletal secretion as has been reported in A. macaronesicus (Ocaña & Brito, 2003) was not found in any other Antipathozoanthus species, including A. tubus sp. nov.
