LM and SEM microphotographs of Halamphora valdeminutissima sp. nov. and Amphora micrometra. 2–10. LM valve views of Halamphora valdeminutissima sp. nov. from the type population (sample C3.1, fig. 6 shows an entire frustule). 11. LM valve view of Halamphora valdeminutissima sp. nov. from a population near Maslen nos Cape (sample M4.3). 12–15. Amphora micrometra, LM views of several valves from the Black Sea, sample M4.3 (Figs 12–14) and sample C3.1 (Fig. 15). 16–18. Halamphora valdeminutissima sp. nov., SEM external views of entire valves, all from the type population (sample C3.1, Fig. 18 represents the holotype specimen). Fig. 16: white arrow indicates the dorsal raphe ledge; black arrow points to the thickening near the central raphe endings. Fig. 17: white arrow indicates the dorsal marginal ridge and black arrow indicates the small semi-elliptic central area on the ventral side. Fig. 18: black arrow points the thickening ventrally to the central raphe endings. 19. Halamphora valdeminutissima sp. nov., SEM internal view (type population, sample C3.1). Black arrow indicates the fused central helictoglossae, and white arrow points to the raphe fissures termination onto a weakly developed helictoglossa. 20. Amphora micrometra, SEM external view of a single valve from the Black Sea (sample M4.3). White arrow indicates the narrow axial area. 21. Amphora micrometra, SEM internal view of a valve from the Black Sea (sample M4.3). White arrows indicate the portulae at each valve apex; grey arrow points the terminal fissures; black arrow shows the fused central helictoglossae. Scale bars: 10 µm (2–15), 1 µm (16–21).
