FIGURE 2. Metadinophysis sinensis: (A–D) Cells from Camamu Bay. (A) Light microscope photograph, left lateral view. (B–D) Scanning electron microscope photographs. (B) Right lateroapical view showing the second (E2) and the third (E3) epithecal plates. Note the straight ventral margin below to left sulcal list (LSL), the convex and crenulate dorsal margin of the left dorsal hypotheca plate (H3), and the posterior pole rounded-truncate. (C) Left lateral view showing the posterior cingular list of the dorsal plate connected to the first rib (R1) of the ventral plate of the hypotheca (arrows), and truncate posterior pole. (D) Sample from Boipeba. Right lateroapical view showing the triangular shape of hypotheca with the two dorsal plates (E2, E3) disposed in different planes. (E–H) Samples from Todos os Santos Bay. (E–F) Epifluorescence micrographs of calcofluor-stained cells. (G–H) Epifluorescence micrographs of calcofluor-stained cells showing red, autofluorescence from discoid chloroplasts. Scale bars = 10μm
