Type species. Gerardia macaronesicus Ocana & Brito, 2003, by original designation. Gender. Masculine. Diagnosis. Sinniger et al. (2010a : 63) originally diagnosed this genus as a group that "grows exclusively on antipatharians" and lacking skeletal secretion. Remarks. No mesogleal canals or sinus, encrustation to outer mesoglea ( Swain and Swain 2014 ), examined species with either branchiform endodermal or endo-meso transitional sphincter muscle ( Swain et al. 2015 ). Sinniger et al. (2010a : 63) discussed that "[t]he type species Antipathozoanthus macaronesicus was originally included in the description of Savalia (Gerardia) macaronesica ( Ocana and Brito 2003), and later the description was amended and the authors suggested the possible placement of this species in a separate genus ( Ocana et al. 2007 ). The species name was accorded to the genus gender. Skeletal secretion (similar to Savalia spp.) was advanced by Ocana and Brito (2003) as occurring in Antipathozoanthus macaronesicus , and this remains to be studied in detail in order to assess whether this is an isolated characteristic or if it is taxonomically informative at genus level." It also appears at least one member of this genus can be found on gorgonian octocorals ( Bo et al. 2012 ).
