Observations
| Observations: | S. Spaulding & R. Esposito |
|---|---|
| Length: | 38.5-54.5 µm |
| Width: | 4-6 µm (center valve) |
| Striae: | 18-21 in 10 µm at the center; 20-23 in 10 µm at the ends |
Description:
Valves linear-lanceolate, narrowing towards the produced, capitate endings; ventral margin concave; dorsal margin parallel to slightly concave. Raphe eccentric, stretching along the valve margin; proximal raphe endings simple; distal raphe endings hooked towards the dorsal margin. Striae parallel throughout; more widely spaced at the center of the valve. Fibulae (keel puncta) variable in size and spacing.
| Morphology: | Nitzschioid |
|---|---|
| Distribution: | South Victorialand endemic |
Notes:
This diatom was usually encountered in girdle view and often with 'hantzschioid' symmetry, although this appears to be a species of Nitzschia. Our specimens were similar to Nitzschia commutata sensu Krammer and Lange-Bertalot (1988), but had a much smaller size range. Our specimens were also similar to Nitzschia stagnorum sensu Hustedt (1930) but were narrower with more capitate endings. Thus, we propose that this is a new species of Nitzschia.
