Length: | 8-10µm |
Width: | 3,5¬5,5µm |
Striae: | 15-18 striae in 10µm on the RV, 12-16 striae in 10µm on the ARV |
Description:
Valves broadly elliptical with rounded ends. (L 8-10µm, W 3,5¬5,5µm, 15 18 striae in 10µm on the RV, 12-16 striae in 10µm on the ARV). ARV : axial area elliptic-lanceolate, fairly large. Transapical striae parallel in the middle, radiate towards the poles, consisting of 1 row of areolae. A very short second row may be present. RV : axial area linear, small. Central area small, rectangular, bordered by short striae. Transapical striae parallel in the middle, radiate towards the poles. Raphe filiform with expanded central endings and very short, slightly deflected terminal fissures.
