Fragilaria striatula Lyngbye ( Figure 28 )

Literature: ( Poulin et al. 1984c, p. 358, figs. 61–66; Witkowski et al. 2000, pl. 28, figs. 1–6).

Description: Length 67 µm, width 3–5 µm, striae 28 in 10 µm.

Remarks: This species has been previously reported from Potter Cove under Synedra kerguelensis Heiden (Al-Handal and Wulff 2008a). Only a single specimen was observed and appeared identical to the images of S. kerguelensis shown in Simonsen (1992, plate 16, figures 4–6) but slightly different from those illustrated in Witkowski et al. (2000) which are rather short and more lanceolate.

Ecology and distribution: A marine benthic species. According to Witkowski et al. (2000), this species is distributed in the Arctic and North Europe. However, it has been widely distributed in Antarctica and the Southern seas ( Heiden and Kolbe 1928; Hendey 1937).
