Abstract

Cymbellonitzschia chilena is described as a new species of diatom. The taxon is characterized by its narrow, arched valves, with a highly convex dorsal side, a concave to sub-linear ventral side, and thin, rostrate-rounded ends. The apical axis measures 20.2–35.0 μm. The marginal raphe canal is continuous, located on either the dorsal or ventral side of the valve. Striae are parallel, with 20-24 in 10 μm. In connective view, the frustule is rectangular and curved. Differences from other species in the genus are also highlighted.
