Family Diploneidaceae Diploneis smithii (Brébisson) Cleve (Figure 62) Literature: (Hendey 1964, pl. 32, fig. 10; Krammer and Lange-Bertalot 1986, p. 291, pl. 112, figs. 2–4; Witkowski et al. 2000, p. 193, pl. 90, figs. 7, 15, pl. 91, figs. 1–2). Description: Length 23–30 µm, width 14–16 µm, striae 14– 16 in 10 µm. Remarks: Only small specimens of D. smithii were encountered, but it might reach up to 200 µm. It is a rather variable species with several varieties described. The common feature which separates D. smithii from closely related taxa such as D. fusca and D. nitescens is the undivided striae which are formed of double rows of alternating areole. Ecology and distribution: A widely distributed marine and brackish-water species, recorded from the sub-Arctic (Cardinal et al. 1984). Rare in Potter Cove.
