Valves linear with large, subcapitate to capitate poles, the latter sometimes wider than the maximum valve width at valve centre. Valve margins tapering slightly towards a small constriction before poles. At valve centre, margins slightly inflated, sometimes unilaterally, or straight. Valve dimensions (n = 20): length 17.5-37.5 µm, width at valve centre: 3.0-3.5 µm. On raphe valve (RV), shape of central area variable, either a small transverse fascia, or oval to round, bordered by one or several slightly shortened striae. Raphe filiform, straight, central pores hardly widened, distantly placed at margin of central area. Central area on rapheless valve (RL) narrow lanceolate. Axial area narrow linear on both valves. Striae radiate throughout on both valves, more distantly placed in valve centre, 30-32 in 10 µm.</p> <p>SEM (Figs 3 A-F; 4A-D)</p> <p>Raphe located on slightly raised sternum, terminal fissures straight terminating at valve/mantle junction. Internally, central raphe endings shortly deflected to opposite sides, terminal raphe endings form small helictoglossae. Striae composed of 2-4 (RV) and 2-5 (RL) areolae. Areolae round or oval, areolae adjacent to valve margin slit-like. Row of transapically elongated areolae on mantle separated from areolae on valve face by hyaline area.</p> <p>On the type slide (lecto-, BM[BM 94890], ex J.R. Carter 3665), the species is common, but many specimens are positioned in girdle view. The central area is often a fascia, as mentioned by Carter (Carter &amp; Bailey-Watts 1981), but sometimes less conspicuous, irregular, and formed by more widely spaced central striae.</p></div> 	https://treatment.plazi.org/id/3B1887D1FF9CFFEEFCEC87DBFB93FAD8	Public Domain	No known copyright restrictions apply.
