Symmetric Biraphid
Scoliopleura
Valves twisted about apical axis
Longitudinal canals on both sides of raphe
Proximal raphe ends deflected in opposite directions
Although the valve margins of Scoliopleura are linear-lanceolate, the frustules are twisted about the apical axis. Longitudinal canals are present on both sides of the raphe. The raphe is slightly sigmoid because of the twist, or torsion, of the frustule. The proximal raphe ends are deflected in opposite directions and the distal raphe...
