Description
Oswaldella tottoni Peña Cantero & Vervoort, 1996
(Fig. 17 g–m)
Material examined. ANT XV/3: 48-194, few stems, up to 120 mm high, with gonothecae; ANT XXI/2: PS65/121, several stems, up to 150 mm high, with gonothecae; PS65/276, few stems, up to 120 mm high, with gonothecae.
Remarks. Only known with female gonothecae from its type locality in the Ross Sea (Peña Cantero & Vervoort 1996), although no sex was attributed by the authors. Material examined here let us confirm a patent sexual dimorphism (Fig. 17m). Male gonotheca, 1.3–1.7 mm high x 0.7–0.8 mm maximum width, cylindrical with rounded end, fusiform in lateral view, with distal, circular aperture. Female gonotheca larger, 2.4–3.0 mm high x 1.2 mm maximum width, inverted cone-shaped, flattened in lateral view, with subterminal, oval aperture.
Ecology and distribution. Species reported from depths between 256 (Peña Cantero & Vervoort 1996) and 400 m (Peña Cantero et al. 1997a); present material from 244 to 277 m. Circum-Antarctic species (Peña Cantero & Vervoort 2004).
