Abstract

A taxonomic survey on the diatoms belonging to the family Fragilariaceae was made, based on 32 samples from the Lagoons Mirim, Flores and. Nicola between 1988 and 1991. Sixteen taxa were identified, two of them being new citations for the Rio Grande do Sul State (Fragilaria neoproducta Lange-Bertalot var. neoproducta and Opephora olsenii Mõeller var. olsenü). Additionally, a new varieta1 combination (Staurosirella leptostauron (Ehrenberg) Williams & Round varo dubia) was proposed.
