Description: Length 71–75 µm, width 15–18, oblique striae at the center 19–21 in 10 µm. Oblique striae cross each other at ca 65° at the center and the raphe curvature is about 19°. Ecology and distribution: This marine species has only been reported from warm waters in tropical and subtropical regions. Its occurrence, although rare in Antarctica , may expand its environmental preferences.
