Pleurosigma eudon var. kerguelensis Heiden et Kolbe (Figure 82) Literature: (Al-Handal and Wulff 2008b, p. 430, figs. 103, 104; Manguin 1960, p. 318, pl. 30, fig. 373; Simonsen 1992, p. 74, pl. 72, figs. 1–5). Description: Length 190–200 µm, width 18–20 µm, transverse striae 20–22 in 10 µm. Ecology and distribution: A marine Antarctic species. Previously reported from Potter Cove both on the sediment and as an epiphyte (Al-Handal and Wulff 2008b). Very rare in the examined material. Pleurosigma strigosum W. Smith (Figure 84) Literature: (Cardinal et al. 1986, p. 187, figs. 70, 72; Hendey 1964, p. 246, pl. 36, fig. 7; Sterrenburg 2003, p. 159, figs. 1– 4, 22–25). Description: Length 145–260 µm, width 18–30 µm, transverse striae 20–24 in 10 µm. Ecology and distribution: A widely distributed marine species, also found in estuaries. Previously recorded from Fuego district in south Antarctica (Frenguelli 1943) and from the sub-Arctic (Cardinal et al. 1986).
