Roy, Kociolek & B. Karthick 2019	<div><p>Ninastrelnikovia lateritica S.Roy, Kociolek &amp; B.Karthick sp. nov. (Figs 1–40)</p><p>LM description (Figs 1–14): —Cells forms colony, bilaterally symmetrical, biraphid. Chloroplast morphology unknown. Valves in valve view appear as narrowly elliptical or lanceolate, gradually inflated in centre. Ends subacutely or narrowly rounded. Length 13.5 – 17.7 μm, central width 3.8 – 4.1 μm, 1.1 – 1.5 μm at the valve apices. Raphe filiform and straight, proximal raphe ends moderately widely spaced, distal raphe ends appearing straight, not curved to the mantle. Axial area narrow, gradually widening towards an apically expanded elliptical central area. Striae distinct and prominent, transapical striae radiate in the valve centre and somewhat wedge-shaped, becoming sub parallel towards the ends, 15 – 16 in 10 μm.</p><p>SEM description (Figs 15–40): —In external valve views (Figs 15 – 28), two types of valves are noticeable. The first type of valve is located on the terminus of the colony and another type of valve is connected to the terminal valve towards the centre of colony. Valves terminating the cell colony (Figs 15 &amp; 16), show fully-developed straight raphe system along with longitudinally-oriented slender siliceous slat system. Instead of spines, this slat system forms pseudo-spines marginally. Another type of valve (Figs 17 &amp; 18) connected with the terminal valve, has a rudimentary vestige of the raphe and peripheral spatulate spines produced between striae. Marginal apical spines are more slender in comparison to other spines (Figs 18 &amp; 19). Slender siliceous slats are missing and spines are partly broken due to cleaning treatment (Figs 17 &amp; 18). Girdle view of a frustule with a terminal epitheca has a spine-bearing hypotheca (Fig. 19). Both apices of terminal valve (Figs 20 &amp; 26) showing distal raphe ends extending onto the valve mantle and curved to the same side. Apex of intermediate valves (Figs 21 &amp; 27) reveals straight and reduced distal raphe ends. Apex of a colony-starting cell (Fig. 22) shows the distal raphe end extending up to mantle, structure of pseudo-spines (arrows) and spatulate spines (arrowheads). Middle part of the terminal valve (Fig. 23) has slightly dilated or expanded central raphe ends, but the central nodule is not visible in between proximal raphe ends and central area is devoid of a silica slat system. Middle part of the intermediate valve (Fig. 24) has wedge-shaped, pleuriseriate striae and rudimentary proximal raphe end. Girdle view of the central area (Fig. 25) shows the marginal spines (marked with arrowhead) and sporadically placed granules (round arrow). Another broken apex of the girdle valve (Fig. 28) of a terminating cell shows the straight raphe fissure (arrow). Some striae in the valve centre are much larger than the others (Figs 15, 17 &amp; 18).</p><p>In internal valve views (Figs 29 – 40), the raphe sternum is absent (Figs 29 &amp; 30). Valve shape variability is shown in Figs 29 – 32. The proximal ends are deflected to the same side (Figs 29 – 33) or appears straight due to weaklydeveloped nature (Fig. 36), while the distal ends terminate as weakly developed helictoglossae (Figs 29, 31, 34 &amp; 35). Internal valves of terminal and intermediate valves have the same set of characteristic features except for the proximal raphe ends. Terminal valve always shows unidirectionally placed proximal raphe ends (Figs 29, 31, 38 &amp; 39). Presence of silica slat system on the outer side of the valves show these are terminal valve. Intermediate valves have both kinds of internal proximal raphe ends, hooked (Figs 32, 33 &amp; 37) and straight (Fig. 36). It is evident in Fig. 32 that another valve is attached (arrows) behind the intermediate valve. Valves shows interdigitating spines located on the valve and mantle junction and these spines support colony formation by interconnecting with adjacent valves (Fig. 36, aroows). However, the valves located inside the colony shows spines with limited growth (Fig. 37, arrows). The terminal valves have hooked ends only (Figs 29, 31, 38 &amp; 39). Striae closed by reticulated pleuriseriate foramina (Figs 36, 37 &amp; 39). Striae have openings that extend to the valve mantle (Figs 29, 31 &amp; 39). Strut-like structures are attached to the mantle (Fig. 40, arrows).</p><p>This biraphid, naviculoid taxon shows an assembly of terminal and intermediate valves. The cells are connected by their valve faces with the help of by marginal interdigitating spines (Figs 19, 32 &amp; 36).</p><p>Type: — INDIA.
