| Summary: | Figs 2–7. Papposphaera heldalii SEM images of cells from the Svalbard region collected during Jan. 2014 (Figs 4–5) and March 2014 (Figs 2–3, 6–7). 2 – cluster of coccoliths shown at high magnification. Notice in particular details of the calyx and coccolith rim calcification. The arrows point to extensions from the pentagonal elements separating the rod-like elements. See also ruptures in the organic base plates of body coccoliths; 3 – whole cell (type specimen) showing the general disposition of types of coccoliths within the coccosphere. A single coccolith (enlarged in Fig. 6) shows the central area calcification of a calicate coccolith; 4 – whole cell. Notice the difference in length of the central process among the two clusters of coccoliths carrying these. See also the conspicuous size differences between neighboring body coccoliths; 5 – body coccoliths showing large individual size differences; 6 – detail of central area calcification in a coccolith that carries a central process (broken away here); 7 ... : Published as part of Thomsen, Helge Abildhauge & Egge, Jorun Karin, 2016, Papposphaera heldalii sp. nov.
