As is typical for the genus, one highly-lobed chromoplast lying with its centre against the ventral side in the girdle but extending beneath every valve with longitudinal indentations (H-shaped); pyrenoid around the dorsal side in the cell (Figure 7k,l). SEM. External and internal views see Figure 8a,b. Standard pattern of the fine structures is principally precisely the same as in other taxa with the genus, especially D. minutus M.J.Wynne. Having said that, the wavy look of fusing areolae externally is much less expressed in our materials most likely as a result of corrosion effects, see Lupeol Epigenetic Reader Domain likewise Figure 8c for D. minutus. Areola density 354 in 10 . Proximal raphe ends deflected towards the ventral side, distal ends strongly bent onto the dorsal mantle, sickle-shaped. Striae inside the subcapitate ends come to be subparallel on the dorsal side, even convergent on the ventral side.Diversity 2021, 13,13 ofTable 2.

Occasionally the location system even seems slightly constricted inside the centre. Raphe strongly reverse-lateral towards proximal ends. Terminal fissures comma-shaped and dorsally bent (see SEM).
