General Environment
This is a marine species.
Description
Valves nearly linear, slightly panduriform, with cuneate apices, 26-52 µm long, 6.3-9.3 µm wide. Raphe strongly eccentric, fibulae distinct, 10-12 in 10 µm, the median two farther apart. Transapical striae developed in the marginal part of the valve, finely punctate, 21-24 in 10 µm. The value surface of N. buschbeckii is distinctly undulate, bearing a keeled raphe at one side and a very shallow mantle on the opposite side. The transapical uniseriate striae are composed of round areolae of varying size. The striae adjacent to the distal side are usually composed of several poroids, whereas the opposite side is marked by a single row of relatively large areolae. The areolae of the striae are elliptical externally but slit-like internally. A very broad sternum interrupts the striae and all striae continue on the sternum outer surface as hyaline depressions separated by ridges and warts. The external raphe terminal fissures are abruptly deflected and the interspaces are small circular or elliptical holes. The fibulae are very broad and plain
Habitat
The species has been so far known only from the area of Mirny Station and from Molodeznaja Station, near the Antarctic continent in the Indian Ocean sector. At both localities, samples were collected from fairly deep sites (38-48 m), the substratum being either rock or rock covered with clay
