Basionym: Cyclotella shanxiensis S.-Q. Xie & Y.-Z. Qi 1984.

Synonyms: Cyclotella shanxiensis S.-Q. Xie & Y.-Z. Qi 1984; Theriotia shanxiensis (Xie & Qi) Kociolek, Q.M. You, Stepanek, R.L. Lowe & Q.X. Wang 2016 .

Original description: Kociolek et al. (2016), p. 276, figs 23–25.

Key literature: Kociolek et al. (2016), p. 276, figs 23–25.

Specimen examined: Tables 1, 2.

Dimension: Diameter 19.6–20.2 μm.

Description: Valves are circular with siliceous granule rows on the external valve face. The granule rows are located between the striae. A hyaline area located near the valve center and valve margin. Striae nearly straight with unequal length and arranged in radial rows around the valve center, 29–36 per 10 μm within a stria near the valve center, 44–60 per 10 μm toward the valve margin.

Remarks: Given the different patterns of granules on the valve, these species might be included in the genus Cyclotella sensu stricto ( Xie & Qi 1984). Edtheriotia species have a perforated center and sessile rimoportulae; its morphology suggests a placement outside Thalassiosiraceae ( Kociolek et al. 2016) .

Distribution and ecology: Edtheriotia guizhoiana is known to occur in waters with high calcium content in South-central China, whereas, Edtheriotia shanxiensis is known to occur in eastern region toward Beijing and in Japan ( Kociolek et al. 2016).
