Gandhi on 6 th March 1945.</p> <p>Lectotype (designated here):—Agharkar Research Institute (AHMA) Gandhi Collection! Slide- Sr 5, here illustrated as Fig. 4.</p> <p>Description:—LM (Figs 1–8): Valves narrowly linear-lanceolate, having large, capitate apices with slight undulate sides (Fig. 5, arrow). 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).</p> <p>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).</p> <p>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 &amp; Kociolek 2012, Kale et al. 2017).</p> <p>Etymology:—The specific epithet “ lacuspowaiensis ” refers to the type locality Powai Lake, Mumbai, where H. P. Gandhi originally collected the sample.</p> </div>	http://treatment.plazi.org/id/E93BC556FFF4DA681DDBC38DE17C7FA6	Public Domain	No known copyright restrictions apply.

Mr. H. P. Gandhi on 14 th August 1949.</p> <p>Lectotype (designated here):—Agharkar Research Institute (AHMA) Gandhi Collection! Slide- Sr 48, here illustrated as Fig. 24.</p> <p>Description:—LM (Figs 19–31): Valves broadly lanceolate with constricted, subrostrate to rostrate apices. Length 32.0–64.0 µm, breadth 12.0–15.0 µm. Axial area narrow, widening at centre. Stauros bow-tie shaped, widening towards valve margin. Raphe slightly coarse with straight central raphe ends, terminal raphe fissures unilaterally deflected. Striae strongly radial punctate, 17–19/10 µm. Areolae punctate to transapically elongated, discernible in LM. (n= 36).</p> <p>SEM (Figs 32–41): Externally (Figs 32–36), valves linear-lanceolate with axial area narrow throughout but wider at centre (Figs 32, 36). Central raphe ends tear-drop shaped (Figs 32, 33). Terminal raphe fissures continuing onto mantle (Figs 34, 35). Striae uniseriate, composed of transapically elongated areolae, 24–28 in 10 µm (Figs 33–35). Internally (Figs 37–41), stauros broad, thickened and expanded (Figs 37, 38, 40). Central raphe ends slightly deflected, terminating onto well-developed stauros (Figs 38, 40). Terminal raphe fissures terminating onto helictoglossae (Figs 38, 39).

Gandhi in the original description- length 54.0–58.0 µm; width 14.4 µm (see Table 2). This taxon is also observed in Sr 46, collected by H. P. Gandhi from the same site at the same time and date as Sr 48.</p> <p>Etymology:—The specific epithet “ dharwarensis ” refers to the type locality Mugad, Dharwar district, Karnataka, where H. P. Gandhi originally collected the sample.</p> </div>	http://treatment.plazi.org/id/E93BC556FFF3DA6C1DDBC38DE1EA7AE0	Public Domain	No known copyright restrictions apply.
