Occasionally one to several shortened striae inserted within the normal striation pattern near the central area (Fig. 2, arrows). Pseudoloculi slightly visible in LM, ca 18 in 10 µm. Partecta distributed along the entire partectal ring, closely attached to the margins without broad flange, reaching almost the apices. Ring composed of partecta of different size (5–6 in 10 µm in the middle, 7–9 in 10 µm near the apices): the middle 6–7 partecta (length 2.4–2.6 µm, width 1.6–3.1 µm) considerable larger than the outer partecta (length 1.2–1.4 µm, width 1.4–1.6 µm).</p><p>Scanning electron microscopy (Figs 6–16)</p><p>External raphe branches clearly undulating (Fig. 6).
