The filamentous desmids are composed of relatively short filaments of cells that dissociate rather easily. These algae are poorly known today in the state of Bahia, being restricted to 13 taxa. This study aimed to do a taxonomic inventory of filamentous genera of the family Desmidiaceae (Zygnematophyceae) from two environmental protection areas, Rio Capivara and Lagoas de Guarajuba, Camaçari municipality, to increase our knowledge of these organisms in Bahia. We analyzed 33 samples collected according to the methods employed in studies of continental microalgae taxonomy. 15 taxa were recorded, distributed in seven genera: Bambusina Kütz. ex Kütz, Desmidium C.Agardh ex Ralfs, Groenbladia Teiling, Hyalotheca Ehrenb. ex Ralfs, Onychonema Wallich, Spondylosium Bréb. ex Kütz. and Teilingia Bourr. Of these, nine are additions to the algal flora of continental Bahia, increasing the total to 22 known species.
