FIGURE 15 in Halamphora oceanica (Catenulaceae, Bacillariophyta), a new species from the epipelagic region of the southwestern Gulf of Mexico
FIGURE 15. Molecular phylogenetic tree based on 18S rDNA sequences (1296 positions included). The tree shows the alignment matrix using the maximum likelihood method. Outgroup taxa were included. Nodal supported values greater than 50% are shown under the branches. Families are according to the taxonomy of Cavalier-Smith (2015).
FIGURES 12–14 in Halamphora oceanica (Catenulaceae, Bacillariophyta), a new species from the epipelagic region of the southwestern Gulf of Mexico
FIGURES 12–14. SEM Halamphora oceanica sp. nov. 12. Longitudinal line exists through the striae near the dorsal margin of the face of the valve. 13. Whole frustule in dorsal girdle view showing girdle bands with two rows of poroids. 14. The same frustule, showing the epicingulum and the association of valve and 4 girdle bands. Scale bars: 2 μm.
FIGURES 6–8 in Halamphora oceanica (Catenulaceae, Bacillariophyta), a new species from the epipelagic region of the southwestern Gulf of Mexico
FIGURES 6–8. SEM Halamphora oceanica sp. nov. 6. External dorsal valve view. 7. Internal whole valve view showing central nodule (arrow) and distal raphe (left arrow). 8. Detail of internal-valve end showing poorly developed helictoglossa. Scale bars: 2 μm (6, 7), 1 μm (8).
FIGURES 9–11 in Halamphora oceanica (Catenulaceae, Bacillariophyta), a new species from the epipelagic region of the southwestern Gulf of Mexico
FIGURES 9–11. SEM Halamphora oceanica sp. nov. 9. Detail of valve apex showing raphe endings curved toward the dorsal side of the valve. 10. Frustule in ventral view. The central area is expanded on the ventral side only and closed with striae near the valve margin. 11. The dorsal striae presented biseriate areola. Scale bars: 2 μm (10), 1 μm (9, 11).
FIGURES 2–5 in Halamphora oceanica (Catenulaceae, Bacillariophyta), a new species from the epipelagic region of the southwestern Gulf of Mexico
FIGURES 2–5. LM. Halamphora oceanica sp. nov. 2. Live material showing a single H-shaped chloroplast. 3. Valve view showing the size and shape, a longitudinal line runs through the striae near the dorsal margin. 4. Whole frustule. 5. Internal valve view. Scale bar = 5 μm.
FIGURE 18 in Halamphora minima (Catenulaceae, Bacillariophyta), new brackish diatom species from the mudflat in Hampyeong Bay, Korea
FIGURE 18. Molecular phylogenetic tree obtained from ML and BI analysis based on rbcL gene showing the phylogenetic positions of Halamphora minima. The values on each node indicate ML bootstrap and Bayesian posterior probabilities (%), respectively. The asterisk indicates 100, and – indicates the topological incongruence between ML and BI trees.
FIGURES 11–17 in Halamphora minima (Catenulaceae, Bacillariophyta), new brackish diatom species from the mudflat in Hampyeong Bay, Korea
FIGURES 11–17. SEM micrographs of Halamphora minima sp. nov. Fig. 11. External whole valve view, with central area (asterisk), and dorsal raphe ledge (arrow). Fig. 12. Internal whole valve view. Fig. 13. Detail of external valve apex,with dorsal raphe ledge (arrow) Fig. 14. Detail of internal valve apex showing tongue-like proximal helictoglossae (double asterisk), poorly developed distal helictoglossae (arrowhead), and internal longitudinal rib (arrow). Fig. 15. Detail of internal dorsal areolae occluded by hymens (arrows). Fig. 16. Dorsal girdle bands with two rows of poroids. Fig. 17. frustules showing the ventral girdle bands with dorsal raphe ledge (arrow). Scale bars: Figs 11—14, 16, 17 = 1 μm, Fig. 15 = 0.5 μm.
