): Frustules in girdle view almost rectangular, weakly clavate with a slightly narrower footpole. Valves lanceolate to rhombic-lanceolate, often asymmetrical to the apical axis. Headpole either not or only weakly protracted, acutely rounded in larger specimens, rostrate to truncated in mid-size to smaller specimens. Footpole always acutely rounded, pointed. Valve dimensions (n=100): length 20–50 μm, width 4.5–7.0 μm. Axial area rather narrow, broader in longer specimens, 1/4–1/5 of the total valve width, linear to linear-lanceolate, not widening towards the central area. Central area asymmetrical, rectangular to slightly wedge-shaped with one shortened stria on one side and one normal stria on the other side. Stigmoid rounded, at the end of the central stria, slightly separated from the last areola. Raphe clearly lateral, undulate. Proximal raphe endings deflected, weakly expanded. Distal raphe fissures hooked. Striae radiate to weakly moderate, becoming parallel near the headpole,
