Diploneis subovalis Cleve ( Figs 173–178 View FIGURES 166–183 )
Valves are broadly elliptic in larger specimens to linear-elliptic in smaller specimens with convex margins and rounded apices. The valve length is 20.0–33.0 μm and the breadth is 9.0–17.0 μm. The axial area is linear to lanceolate expanding into a large elongate central area. The central area is elongate, 2.0–4.0 μm wide. The longitudinal canal is narrow and expanding in the middle of the valve; linear to lanceolate with two rows of areolae throughout its whole length. The raphe is straight and simple, positioned with an expanded depression. Striae are radiate and biseriate, 10–14 in 10 μm, composed of small round areolae, 20–25 in 10 μm, counting along one row of the biseriate pattern.
Ecology and Distribution: —M063A; M272A; M273A; M247A; M276A; M280A: found throughout Lake Hövsgöl at depths of 4 to 40 m on rocks, Chara , epipelon, marl, and sediments .
