Observations

Contributor: Marina Potapova - October 2010
Length Range: 3-15 µm
Width Range: 2.6-4.5 µm
Striae in 10 µm: 40-48

Description

Valves lanceolate to elliptical-lanceolate, with slightly protracted apices, often slightly asymmetric about apical and transapical planes. The smallest valves may become oval. One valve slightly concave, with long raphe slits. The other valve, slightly convex, with distinctly shorter raphe slits and widely separated central endings. Terminal raphe fissures forming a curved opening to the primary side of the valve. Axial area linear-lanceolate, sometimes widening into a small, round or elliptical central area. Transapical striae slightly radiate, becoming parallel or slightly convergent near the poles, 40-48 in 10 μm. Areolae form 3-4 longitudinal rows on each side of the raphe. Outer openings of areolae are transapically elongate, covered by hymenes lying flush with the valve surface. Inner openings of areolae are small, oval foramina.
