description
Samples: GU 55 B- 5 Dimensions: Length 30 µm, width 12 µm, stria density 8 in 10 µm (dorsal) and 13 in 10 µm (ventral)
diagnosis
Diagnostics: More strongly and coarsely striated on the dorsal surface, dorsal striae often biseriate and bifurcating towards the sternum, ventral striae uniseriate.
discussion
Comment: Our specimens (seen also in Yap and Palau) are much shorter than the 68 – 129 µm given by Levkov (2009). A Palauan specimen (Fig. 4) seen in SEM shows that the striae are mostly biseriate, the bifurcations resulting from the two rows diverging; these images conform to the specimens shown by Levkov in SEM.
