Cell body ca. 6.7 µm in diameter. Axopodia three–five times longer than a cell diameter. Plate scales dumbbell-shaped with a median constriction. Circlular lines, parallel to the border of the scale sometimes can be seen. The shafts of spine scales can be straight, but usually it is slightly curved towards the scale base. Length of plate scales 4.4–5.0 µm (ca. 4.7 µm); width 1.62–1.90 µm (ca. 1.71 µm). Spine scales with heart-shaped bases. Sometimes a small circular depression is located on the base at the place of the shaft location. Distal ends of spine scales bear from three to five (usually four) short teeth. Length of spine scales 3.9–6.7 µm (ca. 5.1 µm). Cells tightly attach to the bottom of Petri dish or, very rarely, float. No rolling movement was observed.
