): Valves lanceolate with broadly rounded apices, slightly dorsiventral and heteropolar, commonly asymmetrical about the apical axis with a moderately inflated central portion gradually tapering to the head pole and foot pole. Dorsal and ventral margins similarly arched. Valve length 30.0–36.0 μm, valve width 8.0–13.5 μm, valve length/width ratio varying between 2.6–4.3, median 3.5 (n = 30). Raphe slightly lateral, occasionally appearing slightly reverse-lateral near the central ends, narrowing and becoming filiform towards the distal ends. External central raphe ends deflected gently towards the ventral side, appearing as slightly inflated central pores. External terminal raphe fissures hooked and deflected towards dorsal margin. Axial area very narrow, moderately curved, not or slightly expanded proximally, approximately in the median line of the valve. Central area lacking or not well defined, with one markedly shortened stria near the valve centre. Striae nearly parallel around the valve centre, becoming slightly radiate towards the poles, indistinctly punctate, more widely spaced near the markedly shortened stria, density

They have a length/width ratio that varies between 3.4–5.3, with a median of 4.6. The raphe is lateral and slightly undulate. The axial area is narrow, becoming laterally expanded at the rectangular central area. Striae are radiate, becoming parallel at the apices. Stria density
