Length 98.5 – 103.0 µm, breadth 16.5 – 18.0 µm. Axial area broad widening near centre. Stauros slightly broad, rectangular. Raphe thick with straight central raphe ends, and sickle-shaped terminal raphe fissures with bifurcation (Fig. 7, arrowhead). Striae parallel at centre and radiate towards apices, 18 – 23 / 10 µm. Areolae irregularly punctate (Fig. 4, double arrowheads), discernible in LM. (n = 21). SEM (Figs 9 – 18): Externally (Figs 9 – 14), central raphe ends terminating on stauros (Figs 9, 10, 12). Raphe filiform (Fig. 12). Terminal raphe fissures sickle-shaped, continuing onto mantle (Figs 11, 13). Striae uniseriate, composed of irregularly placed, transapically elongated, slit-like areolae (Fig. 14, double arrowheads). Internally (Figs 15 – 18), stauros small, thickened and elevated with tunnel gap (Figs 15, 17, arrowheads). Terminal raphe fissures terminating onto helictoglossae (Figs 15, 16, 18). Areolae rounded to transapically elongated, 16 – 20 in 10 µm (Fig. 17, double arrowheads).	en	Wadmare, Neha, Karthick, Balasubramanian (2022): Revisiting two Stauroneis Ehrenberg (Bacillariophyta) from H.

E93BC556FFF4DA681DDBC38DE17C7FA6.taxon	discussion	Remarks: — Valve dimensions of the specimens examined in the current study have a smaller size range than the dimensions given by H. P. Gandhi in the original description length 113.4 – 120.0 µm; width 21.6 µm (see Table 1). In addition, previous studies based on Gandhi’s material observed certain morphometry discrepancies (Karthick & Kociolek 2012, Kale et al. 2017).	en	Wadmare, Neha, Karthick, Balasubramanian (2022): Revisiting two Stauroneis Ehrenberg (Bacillariophyta) from H.
