discussion
Remarks: Synonyms: Primnoella magelhaenica: Broch, 1965. This species has been widely reported and figured in Antarctic and sub-Antarctic waters (Bayer 1996 b; Häussermann et al. 2016). It was frequent in several stations of the current study, and is reported as one of the most common species in the Southern Ocean (Auscavitch & Waller 2017). Convexella magelhaenica is a prolific source of natural products, like the dolabellane diterpenoids, new marine product isolated from this octocoral by Rojo de Almeida et al. (2010) with cytotoxic activity against human pancreatic adenocarcinoma cell. Specimens were mostly salmon to red in color, but some also white. Some specimens also showed sparsely branching pattern, not often reported for this species.
