Trieres regia (M. Schultze) Ashworth & E.C. Theriot ( Figs 8–13 View FIGURES 8–13 )

Basionym:— Denticella regia M. Schultze (1859: 21 , pl. 2, figs 11, 12)

Synonyms:— Biddulphia regia (M. Schultze) Ostenfeld (1908: 7 , fig. 3) Odontella regia (M. Schultze) Simonsen (1974: 27) Type:— “North Sea” ( Schultze 1859: 13)

Frustules in girdle view rectangular with narrow tubular elevations at apices and two long spines lying between. Apical axis 90–200μm, areolae 14 in 10 μm ( Hendey 1964, Hasle & Syvertsen 1996). Valves broadly lanceolate with tubular elevation rising from expanded base at each pole ( Figs 8, 9 View FIGURES 8–13 ); occellus at summit ( Fig. 12 View FIGURES 8–13 ). Valve face lanceolate bordered by well-developed marginal ridge ( Fig. 10 View FIGURES 8–13 ) separating it from a deep mantle with distinctly pronounced apices ( Fig. 11 View FIGURES 8–13 ). Two long outwardly directed hollow spines, exterior openings of rimoportulae positioned diagonally between elevations and valve centre. Narrow annulus extending apically between rimoportulae ( Figs 11–13 View FIGURES 8–13 ). Areolae loculate with internal foramina. Biseriate rows of fine pores externally between barely raised costae on mantle; on valve face in a more irregular arrangement of fine pores between scattered spinules transapically meeting at a narrow sternum (see also Ashworth et al. 2013: fig. 4b, e).

Observations:— The description above is based on material from Bonny River, Nigeria (BM).
