Oolina sp. “A”

Figs 3G–I

Description: Test ovoid to elongate-ovoid. Unilocular. Wall ornamented by raised rounded highly polished ribs; flat areas matt. Ribs in elongate hexagonal pattern; pattern can become irregular. Neck surrounded by subcircular ribs. Apical region has slight depression surrounded by thick, circular rib. Aperture terminal, circular to sub-circular on short dome-shaped neck. Width = 155.55 µm, height = 161.11 µm, width:height = 0.97:1.

Material examined: A27401, A27402.

Distribution: Around South Africa from Sea Point to Port Elizabeth. Also recorded off the coast of Namibia by McMillan (1987 a).

Remarks: Similar to O. hexagona as described by Hayward et al. (1999). Differs in the ornamentation around the neck region and the lack of a narrow, distinct neck. Also differs in the irregular pattern on the test. O. scalariformis ( Albani et al. 2001) also has raised longitudinal and transverse costae, however these are more square than the irregular shape of Oolina sp. “A”. O. melo also has raised longitudinal and transverse costae.This species was first identified by McMillan (1987 a) as being different; however, the species was not named as the author was not entirely sure that the species was new. Specimen shown in Fig. 3I , has similar markings and shape to Oolina sp. “A”, and may merely be an abraded Oolina sp. “A” and not a separate species.
