This study aims to identify the taxa belonging to the genus Euastrum present in three Environmental Protection Areas (EPAs) of the coastal plain of the northern Bahia State (Litoral Norte, Lagoas de Guarajuba and Rio Capivara), contributing to the knowledge of the biodiversity of the State and to the geographic distribution of taxa. The analyzed material came from 116 sampling units randomly collected in three EPAs using 20 μm size plankton net and were fixed immediately in Transeau solution. Qualitative analysis and illustrations were conducted with the aid of an optical microscope with digital camera attached. Twenty-three taxa were identified; 17 of them are additions to the desmidioflora of Bahia. Based on this data, the number of taxa recorded for the State raised to 35. Descriptions, illustrations and comparisons with related taxa are presented.
