Morphology and distribution of three araphid diatoms (Fragilariophyceae, Bacillariophyta) from marine coastal waters of Argentina

This study deals with the morphology, taxonomy and distribution of three species of araphid marine pennate diatoms belonging to the Class Fragilariophyceae, Subclass Fragilariophycidae. Material was collected in marine coastal waters from the provinces of Buenos Aires and Río Negro (Argentina) and a...

Material was collected in marine coastal waters from the provinces of Buenos Aires and Río Negro (Argentina) and analyzed using light and scanning electron microscopy.

The distribution of Pravifusus inane and Pseudohimantidium pacifcum is extended southward in the Southwest Atlantic Ocean, and the distribution of Pteroncola inane is extended to the Southwest Atlantic Ocean. The order Protoraphidales Round was validated by providing a taxonomic characterization, as well as indicating the generitype.
