References: Navarro (1982c), p. 248, figs 9–17; Navarro & Lobban (2009), p. 136, figs 58–62; Ashworth et al. (2012), p. 686, figs 1, 5–6, 14–18.

Samples: Moen4_ Halimeda

Dimensions: 82.4 μm long, 7.4 μm wide; 33 striae in 10 μm, 28 areolae in 10 μm.

Comments: The width of the valve and the shape of the apical pore field suggest that this is C. tenuis , rather than the narrower C. tabellariformis Ashworth & Lobban.
