Rectangular cells are interconnected via one or both sides of the valve face, forming zigzag or straight-chain colonies (Figs 1I, J). Valve length ranges from 7.8 to 9.2 μm and width ranges from 2.6 to 3.9 μm. LM reveals that valve outline is linear-elliptical, with the broad and lanceolate central area. Striae are clearly visible, oriented-perpendicular to the sternum, with 19-22 in 10 μm, while the areolae in apical pore fields at both ends are not visible (Figs A–H).</p><p>SEM: The valve outline is linear-elliptical with rounded ends (Fig. 2A). The valve is flat, lacking marginal spines, and curves to form a deep mantle (Figs 3C, 3D, 4, 5). Valves exhibit a distinct and narrow sternum with striae oriented-perpendicular thereupon (Fig. 2A). Striae are arranged in parallel, with 19-22 in 10 μm. Areolae are narrow linear to elliptical, with densities ranging from 111-121 in 10 μm, and C-shaped areolae near the sternum (Fig. 2C). Apical pore fields are located at both ends of the valve, with areolae extending from the valve face to the mantle face, appearing irregularly round or square and diverging towards the mantle (Figs 2B, 3B). The girdle bands are smooth, unperforated and numerous. However, the girdle bands treated with acidization are easy to fall off (Fig. 3C), while those treated with critical point drying are completely preserved (Figs 4, 5). SEM of critical point drying shows that cells secrete gelatinous material via apical pore fields, connecting adjacent cells to form zigzag or straight-chain colonies (Fig. 4); some cells secrete gelatinous material via apical pore fields to form gelatinous stalks (Fig. 5).</p><p>Type.
