Width Range: 5-9 µm
Striae in 10 µm: 16-19
Description
Valves linear, slightly concave in the middle, with the ends protracted slightly and bluntly rounded. Raphe keel strongly excentric, with distinct fibulae numbering 8-11 in 10 µm. Striae appear costate, not distinctly punctate. A longitudinal fold is wide, running the entire length of the valve.

Compare
Tryblionella hungarica is distinguished from T. constricta by the more excentric raphe position, more distinct fibulae and lack of distinctly protracted, elongated apices. It is distinguished from T. calida by its larger size and lack of protracted narrowly rounded apices.

Tryblionella constricta
