Scoliopleura
Grunow 1860 Category: Symmetrical biraphid
TYPE SPECIES: Scoliopleura peisonis Grunow
CLASS: Bacillariophyceae
ORDER: Naviculales
FAMILY: Scoliotropidaceae
- Valves twisted about apical axis
- Longitudinal canals evident on both sides of the 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 ends are divergent. Striae are formed by loculate punctae.
A single species is found in inland waters of high salinity, S. peisonis. Scoliopleura appears to be closely related to Muelleria (Spaulding et al. 1997).
