Monoportula uralensis. Figures 1, reproduction of holotype image of Syndetocystis uralensis from Strelnikova (1974, p. 79, tab. XXVII, fig. 4), “Eastern slopes of Pre-Polar Urals, Severnaya Sos’va River, Ust’-Man’ya Core 82, 145–149.5cm […] diatomite; Campanian, plate XXVII, fig. 4” (Strelnikova 1974, p. 79), Upper Cretaceous (Campanian), rimoportula arowed; Figures 2, 3, LM specimen of Monoportula uralensis from BM 82242, Kuril Islands, Russia, “U.S.S.R. #1” (selected specimen, single mount, rimoportula arrowed); Figures 4–7, SEM, Figure 4, external view of whole valve, rimoportula arrowed, Figures 5, 6, external girdle view of frustule with mantle areolae covered as network of anastomosing costae, Figure 7, detail of Figure 5 showing the long extended tube of the rimoportula, bending towards mantle.

Monoportula uralensis. Figures 8, 9, SEM, internal view of valve with rimoportula arrowed, Scale bars = 10μm (Figs 4, 5, 6), specimens from “Pre-polar Urals #8, Campanian, USSR” ex Strelnikova.

Figure 10a, drawing of Syndetocystis uralensis from Van Heurck (1896, p. 432, fig. 155, after Chase & Walker 1887, pl. 4, fig. 13); Figure 10b is the same drawing modified to remove most of the periplekton leaving just a “thick, hyaline, tubular process”; Figure 10c, the same image as in Figure 5 but reversed, reduced in size and rotated 1800 to aid comparison with Figures 10a and 10b.
