Cylindrotheca closterium (Ehrenberg) Reimann et Lewin ( Figure 90 )

Literature: ( Hendey 1964, p. 283, pl. 2, fig. 8; Reimann and Lewin 1964, p. 289, pl. 124, figs. 1–4, pl. 125, figs. 1–4; Witkowski et al. 2000, p. 374, pl. 212, figs. 4–6 [both as Nitzschia closterium ]).

Description: 72–80 µm, width, 4.5–5 µm.

Remarks: Species with delicate frustules which often get destroyed in routine cleaning of diatoms.

Ecology and distribution: A widely distributed benthic species and very common in sea-ice diatom communities both in Antarctica ( Kang and Fryxell 1992) and the Arctic ( von Quillfeldt 2000). Rare in Potter Cove.
