Description

Relatively large anemone attached to nodule. Column pale, white, with verrucae arranged in rows. No pronounced limbus. Morphology and colour of tentacles not observed (Fig. 10).

Genetic data for this taxon with new GenBank accession numbers are provided in Table 2.

Diagnosis

Assigned here to the family Hormathiidae Carlgren (1932) based on morphology, and most similar to species in the genus Phelliactis Simon (1892) (Estefania Rodriguez pers. com.). Attempts to collect a full suite of genetic marker data was unsuccessful, and limited to the 18S gene only. A phylogenetic analysis of the 18S gene including hexacoral taxa available at Genbank placed this specimen with low support as sister to a sequence assigned to Capnea georgiana ( Carlgren 1927). The result is most probably an artefact due to the restricted dataset and homoplasy in the 18S gene. Previous analyses has suggested limitation of this gene alone for species barcoding and genus level phylogenetic reconstruction in hexacorals ( Rodríguez et al. 2014).
