Cocconeis kerguelensis Petit (1889): 116, pl. X, fig. 5 — Cleve (1895): 182; Bourrelly and Manguin (1950); Desikachary (1988): 7, pl. 506, figs. 1–12.
Description
Valves elliptical, disc-like, length 53.1 (32–55) µm, width 47.9 (38–85) µm. SV: axial area relatively narrow, linear-lanceolate. Striae biseriate, 7 (4–6) in (10) µm, 4 striae at margins, slightly parallel at centre and highly radiate at apices. Areolae 16 (10) in 10 µm. RV (not imaged): raphe ends near margin. Axial area very narrow. Central area has transverse, outwardly narrowed fascia. Striae biseriate, 4 in 10 µm. Areolae 10–12 in 10 µm and crossed near margin by narrow blank band.
Diagnosis
The description above is based on Cleve (1895) and matches well with the images in Desikachary (1988). Only one image of the sternum valve.
