Nitzschia australis (M. Peragallo) A. Mann (Figures 94, 95, 118) Literature: (Mann 1937, p. 63, pl. 6, fig. 1; Peragallo 1921, p. 65, pl. 3, figs. 17, 18 as N. dubia var. australis Scott and Thomas 2005, p. 187, fig. 2.107a–f). Description: Length 70–85 µm, width 7–10 µm, fibulae 14– 16 in 10 µm. Remarks: Striae are very fine but look coarser at valve center. Both Peragallo and Mann (cited above) reported 19– 20 striae in 10 µm while Scott and Thomas (2005) recorded 19–25 in 10 µm. The observed specimens appeared to have less dense striae. This Antarctic species has rarely been reported and described in recent literature. Ecology and distribution: Antarctic marine species. Rare in Potter Cove.
