Natatolana intermedia (Vanhöffen, 1914) Cirolana intermedia Vanhöffen, 1914: 500, fig. 37.– Tattersall, 1921: 205.– Hale, 1937: 17.– 1952: 27.– Kussakin, 1967: 224. Natatolana intermedia .– Bruce, 1981: 958.– 1986: 222.– Brandt, 1988: 113, figs. 51–55.– Brusca et al ., 1995: 80. Type material . Lectotype designated by Brandt (1988): 3, 15.5 mm, originally ZMG but now in SIF ZMG 260 (not examined). Paralectotypes: 3, 17 mm, 4♀♀, 13 mm, 14 mm, 15 mm, 16 mm, SIF ZMG 261 (not examined). Also, 233, ZMUC CRU158; 2♀♀, ZMUC CRU159; apparently part of original syntype series from the type locality donated by the ZMB in 1926 (examined). Other possible paralectotypes are ZMB 17618 (male and 2♀♀) ZMB 17620 (male and 6♀♀); all from type locality (Brandt, 1988) (not examined). Type locality: off Gauss Station, Posadowsky Bay, Antarctica, 66°2.9'S 89°38.5'E, 385 m, [Deutsche Sudpolarexpedition 1901–1903]. Diagnosis . Eyes : well developed; elongate, length c. 2× height. Interocular furrow : weakly developed, indistinct and not extending across the cephalon. Frontal lamina : lateral margins straight, narrowing anteriorly. Antenna : c. 0.33– 0.4× as long as body, reaching to between the posterior of pereonite 3 and 4. Coxal plates : furrows strongly developed, on all coxae. Pleonite 4 : posterodorsal margin strongly concave proximal to meeting posteroventral margin at apex; apex forming a narrow acute point. Pleotelson : broad, length 0.92× basal width; anterodorsal depression absent (there is an indistinct depression but this is not as distinct and abrupt as in species such as N. pellucida ); anterolateral margins convex; posterolateral margins convex; apex produced into a small point; with 10–16 RS. Pereopod 2 : propodus with 3–4 RS on palm. Pereopod 3 : propodus with 3–6 RS on palm. Pereopod 7 : basis narrow, width 0.45× length; distance between anterior margin and medial carina less than between posterior margin and medial carina; posterior margin with setae along entire length. Penes : present. Pleopod 2 appendix masculina ...
