(Figs 2–27)</p><p>Light microscopy (Figs 2–21):— Valves elliptical to oval, with broadly rounded apices, never protracted. Valve dimensions (n = 30): length 5.1–11.5 µm (7.4 ± 1.8 µm), width 2.5–3.0 μm (2.8 ± 0.2 µm). Raphe branches filiform, slightly curved toward the ventral side of the valve, with polar and central nodules visible as white or dark dots (Figs 1, 3). Striae: 30–32 striae in 10 μm, hardly discernible and shortened in the middle of the valve (Figs 3, 9).</p><p>Scanning electron microscopy (Figs 22–27):— Axial area narrow, linear. Central area wide and symmetrical, rectangularly shaped, bordered by 2–3 shortened striae. Raphe filiform with short, straight or weakly deflected external proximal raphe endings (Fig 23). Distal external raphe fissures hooked and deflected to the same side of the valve (Figs 22, 23). Internally, proximal raphe endings straight or slightly deflected and distal raphe endings terminating in small helictoglossae (Fig 26). Striae uniseriate, parallel or weakly radiate throughout and shortened in the middle of the valve, composed of 2 to 4 areolae rounded areolae, covered externally by porous hymens, and interrupted by a hyaline line at the valve face/mantle junction (Figs 22, 23).</p><p>Type: Locality— ITALY. <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=9.121555&amp;materialsCitation.latitude=40.42339" title="Search Plazi for locations around (long 9.121555/lat 40.42339)">Benetutti</a>: San Saturnino, 252 m a.s.l., 40°25’24.2’’N, 009°07’17.6’’E), Habitat: epipelon, Sampling date: 03 July 2016, sample collected by Giuseppina Grazia Lai, Holotype: Permanent slide n° BR-4684 deposited in the Diatom Collection of the Meise Botanic Garden, Belgium, specimen depicted in Figs 2, 3.</p><p>Etymology:— The specific epithet refers to the Mediterranean island of Sardinia.</p></div>	https://treatment.plazi.org/id/C74087F6223F2A0BE6CCFB5EFBA83B60	Public Domain	No known copyright restrictions apply.
