Acanthopolymastia acanthoxa (Koltun, 1964) (Fig. 2) Synonymy Atergia acanthoxa — Koltun 1964: 27, fig. 3. Acanthopolymastia acanthoxa— Kelly­Borges and Bergquist 1997: 396, fig. 27; Boury­Esnault 2002: 209, fig. 7. Not Atergia acanthoxa— Lévi 1993: 26, fig. 7C, pl. II (9–12). Material examined SMF 10539 (1 specimen): PS67/080­6. Description External morphology. Slightly damaged, cushion­shaped sponge measuring about 13x13 x 5.5 mm and removed from substrate (fig. 2A). The upper surface of the sponge is mainly hispid, where not damaged. Its colour is greyish due to sediment particles, which soil the hispidation. Bare areas of the surface are paler. The basal surface is rather damaged. The marginal spicule fringe is well preserved and measures about 6 mm in width. A single exhalant papilla is pale and measures approximately 1 mm in length and 2 mm in diameter. The cortex is semi­transparent, hardly detachable, moderately firm and somewhat fragile. The choanosome is soft, crumbly and whitish in colour. ... : Published as part of Plotkin, Alexander S. & Janussen, Dorte, 2008, Polymastiidae and Suberitidae (Porifera: Demospongiae: Hadromerida) of the deep Weddell Sea, Antarctic *, pp. 95-135 in Zootaxa 1866 on pages 98-99, DOI: 10.5281/zenodo.183878 ...
