FIGURES 14–20. SEM images of Hippodonta fujiannensis. Figs 14, 17, 18. External view of entire valve. Striae uniseriate throughout the valve face and mantle. On one valve side, one column of lineolae closest to the raphe is positioned perpendicular towards remaining lineolae of the striae. Figs 15, 19. Close up of valve apices. Terminal endings of raphe distinct, strongly pronounced, teardrop-shaped depressions, positioned before terminal area or weakly advancing into it, slightly curved towards one valve side. Figs 16, 20. Close up of the central area. Central endings of the raphe small, teardrop-shaped depressions; central endings are positioned close together. Central area dissymmetrical. Scale bars in Figs 14, 18 = 5 μm; Fig. 17 = 2 μm; Figs 15, 16, 19, 20 = 1 μm.
