Resumo: 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 analyzed using light and scanning electron microscopy. Pravifusus inane (Giffen) Garcia and Pteroncola inane (Giffen) Round, were found in the water column, and Pseudohimantidium pacificum Hustedt & Krasske was recorded as epizoic on planktonic copepods. The three genera are cited for the first time in Argentina, and Pteroncola inane for first time in the South Atlantic Ocean. The distribution of Pravifusus inane and Pseudohimantidium pacificum 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.

O material foi coletado em águas costeiras marinhas das províncias de Buenos Aires e Río Negro (Argentina) e analisados por meio de microscopia óptica e eletrônica de varredura. Pravifusus inane (Giffen) Garcia e Pteroncola inane (Giffen) Round foram encontradas na coluna d’água, enquanto Pseudohimantidium pacificum Hustedt & Krasske, foi registrada como epizoica em copépodos planctônicos. Os três gêneros são citados pela primeira vez para a Argentina e Pteroncola inane pela primeira vez para o Oceano Atlântico Sul Ocidental. A distribuição de Pravifusus inane e Pseudohimantidium pacificum é estendida para ao sul do Oceano Atlântico Sul Ocidental e a distribuição de Pteroncola inane é estendida para oOceano Atlântico Sul Ocidental. A Ordem Protoraphidales Round foi validada fornecendouma caracterização taxonômica, bem como indicando o gênero tipo.Iheringia.
