Cocconeis dallmannii Al-Handal, Riaux-Gobin, Romero et Wulff (Figure 50) Literature: (Al-Handal et al. 2008, p. 275, figs. 33–47, 49–62). Description: Length 24–30 µm, width 18–22 µm, striae (raphe valve) 10–11 in 10 µm. Remarks: This species has originally been described from Potter Cove Al-Handal and Wulff (2008b). The observed specimens appeared slightly larger than previously reported with coarser striae on the raphe valve. Ecology and distribution: A marine benthic and epiphytic species, it has not been reported outside its type locality (Potter Cove). Rare in the examined material. Cocconeis fasciolata (Ehrenberg) Brown (Figure 51) Literature: (Riaux-Gobin and Romero 2003, p. 26, figs. 26– 28, pl. 19, figs. 1–11; Scott and Thomas 2005, p. 127, fig. 2 [68 a–d]). Description: Length 41–48 µm, width 27–32 µm, striae (rapheless valve) 4–5 in 10 µm. Ecology and distribution: A marine periphytic species. Although it was recorded from North Europe, the species seems more distributed in the Antarctic Peninsula (Scott and Thomas 2005). Frequent in Potter Cove.
