Entopyla ocellata (Arnott) Grunow ( Figures 37, 38 View Figures 27–38 , 109– 111 View Figures 107–112 )

References: (Al-Handal and Wulff 2008b, p. 427, figs. 57– 62, 65; Desikachary 1988, p. 11, pl. 584, figs. 10, 11).

Description: Length 48–75 µm, width 10–16 µm, striae 4–6 in 10 µm.

Remarks: This species is characterized by having large and wide apical pore fields occupying two thirds of the concave valve face ( Figures 109, 110 View Figures 107–112 ). A very narrow sternum (not visible under LM) runs from pole to pole. Two rimoportula open externally as small, elongated openings located centrally under each pore field and internally as large crescent-like openings located transversely with short stalks ( Figure 111 View Figures 107–112 ) which are very characteristic for this species.

Ecology and distribution: A marine epiphytic or benthic species. Widely distributed as epiphyte in King George Island (Al-Handal and Wulff 2008b). Frequent in the present material.
