Type Species
The type species (holotype) of the genus Nitzschia is Nitzschia elongata Hassal.
Status of Name
This name is of an entity that is currently accepted taxonomically.
Type Information
Type locality: Victoria Docks in Hull (UK); (Witkowski & al., 2004: 584) Holotype: (Witkowski & al., 2004: 584) Notes: Holotype: Slide 2788 in Herbar Grunow (AWH); deposited in Dr Henri van Heurck Museum in Antwerp (Belgium). Witkowski et al. (2004) note that the type preparation was found in Dr Henri Van Heurck Museum in Antwerp, Belgium, in a paper package bearing the note 'Nitzschia subconstricta Grunow'. This name has never been validly published. They also note that the sample was supposedly collected by R. Hennedy in 1858; it was passed either to A. Grunow or H. Van Heurck by Prof. G. Walker-Arnott from Glasgow.
General Environment
This is a marine species.
Description
Valves nearly linear, slightly panduriform, with cuneate apices, 10-57 µm long, 5-9 µm wide. The valve surface of N. ligowskii is distinctly undulate, bearing a keeled raphe on one side and a very shallow mantle on the opposite side. Raphe strongly eccentric; the external apical endings are abruptly deflected. The fibulae are distinct, 12-15 in 10 µm, broad and plain, and the median two are father apart than the others. Transapical striae are present in the marginal part of the valve, finely punctate, 22-27 in 10 µm; they are composed of round poroids of variable size. The striae adjacent to the distal margin are usually composed of several poroids, whereas on the opposite side, on the proximal mantle, there is a single row of relatively large areolae. The stria-forming areolae are elliptical externally but slit-like internally. A very broad sternum interrupts the striae and all striae continue on the sternum surface as hyaline depressions separated by ridges and warts
