Collector: Laura Schejter. Description. Our specimens are massive, light brown to slightly grey, 64 x 23 x 24 mm (Figure 5 A). Spicules are 2 categories of styles (sometimes subtylostyles), occasionally basally-spined, 350–(415±45)–487 x 7.5 µm and 515–(603±50)–780 x 12.5–(17±3)–20 µm (Figure 5 B); acanthostyles (Figure 5 B, C), 105–(130±16)–146 x 5 – (8±2)–10 µm and short; thick and wing-shaped toxas, 45–(57±6)–71 µm (Figure 5 C–D). Few rare and big toxas (250–370 µm) were also found (Figure 5 D). Distribution. This species has a wide distribution in the SW Atlantic Ocean and southern Pacific, recorded from Antarctic waters, South Georgia Islands, Malvinas (Falklands) Islands, off Buenos Aires and Uruguay, Macquarie Island and New Zealand, (Hooper 2009; Schejter et al . 2011).

Later, Hooper (1996) demonstrated that “ antarctica ” should be used against “ toxifera ”, and confirmed the synonymy between “ basispinosa ” and “ toxifera ”, rejecting the inclusion of C. pauper; however, he did not confirm the inclusion of “ tuberculata ” because the types were not found. Also, the new combination proposed for this taxon was Clathria ( Microciona ) antarctica (Topsent). Goodwin et al .
