Trieres sinensis (Greville) Ashworth and E.C. Theriot ( Figs 14–20 View FIGURES 14–20 )

Basionym:— Biddulphia (‘Chinesis’) sinensis Greville (1866: 81 , pl. 9, fig. 16)

Synonyms:— Odontella View in CoL (‘Chinesis’) sinensis (Greville) Grunow (1884: 58) Denticella sinensis (Greville) De Toni (1894: 884) Zygoceros chinensis (Greville) Cleve (1901: 31)

Type:— “Harbour of Hong Kong; J. Linton Palmer, Esq.” ( Greville 1866: 81) ( BM 2998, syntypes, see Williams 1988: 18).

B.” in Bailey (1851: figs 34 and 35) (not to scale).

Frustules in girdle view rectangular with short tubular elevations at apices and long, tubular spine at base. Apical axis 90–260μm, transapical 60–80 μm, areolae 16–18 in 10 μm (after Hendey 1964, Hasle & Syvertsen 1996). Valve broadly lanceolate with rounded apices and short tubular elevations at each pole with ocellus at summit ( Figs 14, 15, 19 View FIGURES 14–20 ). Valve face narrowly lanceolate bordered by narrow marginal ridge separating valve face from distinctly expanded mantle ( Fig. 14 View FIGURES 14–20 ). At base of each elevation lies an outwardly directed tubular spine lying on a raised base ( Fig. 15 View FIGURES 14–20 ), exterior opening of rimoportula ( Fig. 18 View FIGURES 14–20 ). Areolae loculate, mantle exterior with bi- and tri-seriate rows of fine pores bordered by barely raised costae that span entire depth of mantle ( Figs 16. 17 View FIGURES 14–20 ). On valve face in similar pattern, in transverse rows, those at pole broken by central sternum extending ¼ length of valve face ( Fig. 20 View FIGURES 14–20 ). Circular pores with raised rims scattered over valve face and mantle ( Fig. 16 View FIGURES 14–20 ).

Observations:— Lavigne et al. (2016: 320–324) provide images of the living cell with ‘small discoid chloroplasts’ ( Lavigne et al. 2016: figs 85–90). For further details on this species see Ashworth et al. (2013: fig. 4c, f).

The description above is based on material from “Wunderluss” (locality unknown, ex Brigger colln, BM).
