dc:description"Figures 1–17: Light micrographs of Craspedostauros lateralis sp. nov. and C. cf. laevissimus of different sizes. (1–9) Craspedostauros lateralis. (1–8) Showing the distinct constriction of the valve and the shape of the stauros. (9) A small valve with elliptic outline.(10–17) Craspedostauros cf.laevissimus. (10–12) Valves with parallel margins. (13, 14) Valves with slightly inflated valve halves. (15) Valve with slightly swollen at the centre. (16) Small elliptic valve. (17) Frustule in girdle view showing constriction and cingular bands. Scale bars = 10 μm.";

(20) Middle part of the valve interior showing the depressed areas on both sides of the axial area (arrows) and the characteristic triangular constriction of the valve which is an extension of the central area (fascia). (21) The two irregular hyaline areas (arrows) which form the junction line between valve face and the mantle. (22) Internal side of the valve pole exhibiting the distal raphe ending. (23) External side of the valve pole with the curved distal raphe ending.(24) Elongated areolae on both sides of the axial area with numerous cribral pores. (25) External openings of the areolae with 4–5 peripheral cribral pores. (26) Valve in girdle view.
