9FCA09E0E304555E8739D0D09BD664CC.taxon	description	Description. LM (Fig. 2). Valves relatively big, linear to linear-lanceolate, with gradually narrowing, rounded apices. Length 27.7 - 30.4 µm, breadth 3.3 - 4.0 µm. Raphe straight, filiform. Striae on the raphe valve radiate, uniseriate, 27 - 28 in 10 µm, consist of round and narrow elongated areolae. On the rapheless valve the central and axial areas are absent. Striae are almost parallel, 26 - 27 in 10 µm, becoming noticeably more radiate near the valve apices. Areolae not resolved in LM. SEM (Fig. 3). External proximal raphe ends simple, distal raphe ends straight. Internal proximal raphe ends slightly bent in opposite directions, distal raphe ends terminate is weakly developed helictoglossae. Raphe positioned in a narrow axial area that slightly widens near the centre of the valve. A distinct central area is absent, but 2 or 3 striae in the center of the valve are spaced wider than the majority of the striae. Areolae are mostly elongated.	en	Tseplik, Natalia D., Maltsev, Yevhen I., Glushchenko, Anton M., Kuznetsova, Irina V., Genkal, Sergei I., Gusev, Evgeniy S., Kulikovskiy, Maxim S.
