Description Cells ovate and ventrally slender. Antero-posterior length nearly equal to the transdiameter (width). Dorsoventral diameter 1.5 to 2 times larger than transdiameter. The shape and configuration of thecal plates are similar to those of O. siamensis. Thecal plates with numerous minute pores visible in LM. The size of 0.07 μm given by Faust et al. (1996) is probably mistaken. In the Mediterranean Sea and Atlantic Ocean, Penna et al. (2005) found specimens smaller than O. ovata and genetically different from the Pacific populations. They named it O. cf. ovata and reported pores ranging from 0.16 to 0.55 μm in two classes: 0.25–0.30 μm and 0.45–0.50 μm. Smaller pores were also observed in this taxon, but they can not be resolved in LM. [details]
